The python print is one of the built-in functions used to display the given value as an output. If you want something to be written o the screen or output device, then you have to use this Python print function.
In this section, we explain to you how to use this Python print function of the standard library with multiple examples. The basic syntax behind this Python print function is
print(value,……., sep = ‘ ’, ends = ‘\n’, file = sys.stdout, flush = False)
Let me see the detailed information behind this Python print function arguments:
- Value: This Python print function display this value to output or writes it to a file using file argument.
- sep: It’s an optional argument. If you specify any string then that string value inserted between values. By default, this value is space.
- end: It’s an optional argument. If you have given any string, then that string is appended after the last value. The default value is a newline (\n).
- file: This is an optional argument. You can use this to display the output in a text file or something like that. By default, it uses sys.stdout (standard output)
- Flush: Change it to true if you want to flush the stream forcibly.
Python print statement examples
In Python print function, you can use either a double quotation or a single quotation or combination of both to return the string literals as an output.
In this example, for the first statement we are using it to display Hello world as an output. Remember, the print statement is the standard output device that prints blank line by default.
Within the second line, we are displaying three individual strings separated by comma. As we said earlier, it uses space as the default separator for string concatenation.
print("Hello World")
print("Learn", 'Free', 'Programming')
Hello World
Learn Free ProgrammingUse the Python print function without any argument to return an empty line because, by default, it uses a newline as the argument value.
I think you may not notice the empty spaces in the previous example. So, I suggest you to use this method in-between any of the statements.
variables in print statement
When you are calling a variable or displaying the variable value, you have to call its name without any quotations in the Python print function. Here, we declared a number and assigned 100. Next, we called that number without quotation and with a quotation.
The first Python print function statement is calling the variable number value. The second one is stamping the word number. So, please be careful while calling the variable values or list values, etc.
Python print List, Tuple, Set and Dictionary
Using this Python print function to display the items in Lists, Tuples, Sets, and Dictionary. As you can see from the below, we created a list, two tuple, set, and a dictionary. Next, we used it to display them.
If you want to access each item individually or to perform operations on each item, then use For Loop along with range Function.
numbers_list = [10, 20, 30, 40, 50]
print(numbers_list)
fruits_tuple = ('apple', 'cherry', 'kiwi', 'mango')
print(fruits_tuple)
mixed_Set = {'banana', 1, 2, (1, 2, 3)}
print(mixed_Set)
myDict = {'name': 'Kevin', 'age': 25, 'job': 'Developer'}
print(myDict)
Output of the list, tuple, and set items
[10, 20, 30, 40, 50]
('apple', 'cherry', 'kiwi', 'mango')
{1, 2, (1, 2, 3), 'banana'}
{'name': 'Kevin', 'age': 25, 'job': 'Developer'}Python print sep example
By default, this function uses the empty space as the separator. However, you can override this with any of your own string. The first statement in this Python print sep example uses * as the separator between two strings Hello and World.
print("Hello", "World", sep = "*")
Hello*WorldPython print end parameter example
How to use this print statement without a blank line?. By default, the range function uses the new line as the end argument value. However, you can override it. In the above Python print function example, the two statements displays the strings in two different lines.
Here, we used the end parameter with space as the value and the second statement with . as the argument value. It means, after stamping the Welcome to, space appended. Next, the fifth statement display the Tutorial Gateway after that space, and the statement ends with.
print('Welcome to', end = ' ')
print('Tutorial Gateway', end = '.')
Welcome to Tutorial Gateway.end and sep arguments
In this Python print statement arguments example, we are using both the sep argument and the end argument. From the below, (10, 20, 30, sep = ‘ @ ‘, end = ‘ **** ‘) returns 10 20 30 separated by @ symbol and ends with **** within the same line. Similarly, (‘A’, ‘B’, ‘C’, sep = ‘ , ‘, end = ‘ ##### ‘) statements returns A B C separated by comma and ends with ##### in the same line.
print(10, 20, 30, sep = ' @ ', end = ' **** ')
print('A', 'B', 'C', sep = '--')
print('A', 'B', 'C', sep = ' , ', end = ' ##### ')
10 @ 20 @ 30 **** A--B--C .
A , B , C #####It is another example of the function with keyword arguments. Here also, we used this along with the separator argument and the end argument.
For example, (‘Number = ‘, num, sep = ‘0000’, end = ‘?\n\n\n’) display number separated by 0000 and ends with ? and three new lines.
num = 1234
print('Number = ', num, sep = '0000', end = '?\n\n\n')
Number = 00001234?
For Loop Example
Use this function inside the For Loop along with Range Function. By this, you can display the items within a given range — the first statement returns numbers from 1 to 9. You can also use the end argument to display the numbers in one line. For instance, (i, end = ” , “) separate the numbers by command displays them in one line.
for i in range(1, 10):
print(i)
1
2
3
4
5
6
7
8
9Python print String Format
We are using this function along with conversion types. Within the first statement, we used two %s in between a string follows by a tuple with variables. It replaces those two %s items with those tuple values.
Here, it uses the same order that we specified. I mean, first, %s is replaced by a person variable, and the second %s replaced by name variable value. Here, (person +’ is working at ‘+ name) statement is to concat three items.
name = 'Tutorial Gateway'
person = 'suresh'
year = 2019
print('%s is working at %s' %(person, name))
print(person + ' is working at ' + name)
string formatting output
suresh is working at Tutorial Gateway
suresh is working at Tutorial GatewayPython print format Example
In this example, we are using the format function inside this function. It allows us to format values. I suggest you refer to the format Function article.
name = 'Tutorial Gateway'
person = 'suresh'
year = 2019
print('{0} is working at {1}'.format(person, name))
print('Copyright {} at {}'.format(name, year))
suresh is working at Tutorial Gateway
Copyright Tutorial Gateway at 2019Special Characters in Python Print Statement
It allows you to use special characters by using escape characters. For example, within s1 (‘Hi there, \ “How are You?\”‘), we used \ character to escape double quotes within the statement. Next, we used \ to escape ‘(single quote) in (‘I Don\’t Know you’).
s1 = 'Hi there, \"How are You?\"'
print(s1)
print('I Don\'t Know you')
Hi there, "How are You?"
I Don't Know youIn this example, we are using the New Line, Horizontal Tab, Vertical Tab, etc., in between a string to show you how they alter the output. For example, the first statement with \n display Hi there, in the first line and How are You? in the next line.
With New Line, Horizontal Tab, and Vertical Tab output
Similarly, if we use the \n for the empty lines as well. For instance, (3 * “\n”) returns three new lines. And the (“\n\n\n\n\n”) statement stamps 5 new lines.
Conversion Types in Python print statement
The list of conversion types that are available in the Python print statement.
- %c – Returns a Single character.
- %d – Returns a Decimal Integer
- %i – for Long integer
- %u – Returns an unsigned decimal integer
- %e, %E – Returns the floating-point value in exponential notation.
- %f – Returns the floating-point value in fixed-point notation.
- %g – Returns the shorter value of %f and %e
- %G – Returns the shorter value of %f and %E
- %c – Returns a Single character
- %o – Returns an Octal value
- %r – Generates string with repr()
- %s – Converts the value to a string using str() function.
- %x, %X – Returns the Hexadecimal integer.
Let me use all the available conversion types in one example. For this, we declared a few variables with a numeric value 100000, string text = ‘Tutorial Gateway’, decimal value science = 1.20023456341, and a character cr = ‘u’.
Python print file example
Here, we are opening a file Sample.txt (if it exists). Otherwise, it creates that text file in the default directory. Next, the it display the statement inside that text file object.
file_name = open('Sample.txt', 'w')
print('Welcome to Tutorial Gateway', file = file_name)
file_name.close()
After running the above script, if you open the text file, it has that message Welcome to Tutorial Gateway.
