Python Split String

Split

Python Split string function is one of the Python String Method which is used to split the given string and return a list of words. This function accepts two arguments (optional) and if you specify the separator to split then it will use the specified separator to return a list of words. Python String Split function will start looking for the separator from Left Hand side and once it finds the separator, it will split the string before the Separator and add to list item. It will repat the process until it reaches to end position or Max_Split position. In this article we will show you, How to write String Split in Python Programming with example.

Syntax of a Python Split String Function

The basic syntax of the Python String Split function is as shown below:

1	String_Value.split(Separator, Max_Split)

String_Value: Please select the valid String variable or you can use the String directly.
Separator: This argument is optional and if you forget this argument, python will use Empty Space as the separator.
Max_Split: This argument is optional. If you specify this value then, split function will restrict the list of words.

Return Value

Python String Split function will return List of words. For example, If we have X*Y*Z and If we use * as separator, Split function will search for * from left to right. Once it find * it will return the string before the * symbol as List Item 1 (X) so on and so forth.

If you add Max_Split argument to above example, X*Y*Z.split(‘*’, 1), split function will search for * and Once it find * it will return the string before the * symbol as List Item 1 (X) and return the remaining string as list item 2.

NOTE: If you pass the non existing item as the separator then it will return the whole string as List Item 1.

Python Split String Example

The following set of examples will help you understand the String Split in Python Programming Language. Here we will only Pass either single argument or No argument to the split function

PYTHON CODE

# Python Split String Example

Str1 = 'India, China, Japan, USA, UK, Australia, Canada'

Str2 = 'Learn-Python-Programming-Tutorial-Gateway'

Str3 = 'xyz*abc*ijk*lmn'

Str4 = Str1.split(',')

print("After Splitting String 1 = ", Str4)

Str5 = Str2.split('-')

print("After Splitting String 2 = ", Str5)

Str6 = Str3.split('*')

print("After Splitting String 3 = ", Str6)

#Performing Python Split function directly

Str7 = 'https://www.tutorialgateway.org/python/'.split('/')

print("After Splitting String 7 = ", Str7)

# Split function with No arguments

Str8 = 'Learn Python Programming Tutorial Gateway'

Str9 = Str8.split()

print("After Splitting String 8 = ", Str9)

OUTPUT

ANALYSIS

First we declared three String variable Str1, Str2, Str3 and assigned corresponding value using following statement

Str1 = 'India, China, Japan, USA, UK, Australia, Canada'

Str2 = 'Learn-Python-Programming-Tutorial-Gateway'

Str3 = 'xyz*abc*ijk*lmn'

Following statement will split the Str1 string based on the separator we specified (i.e, ‘,’) and prints the output.

1 2	Str4 = Str1.split(',') print("After Splitting String 1 = ", Str4)

Following statement will split the Str2 string based on the ‘-‘ symbol and prints the output.

1 2	Str5 = Str2.split('-') print("After Splitting String 2 = ", Str5)

Below statement we used the Python String Split directly. Following statement will split the string based on the ‘/’ symbol and prints the output.

1 2	Str7 = 'https://www.tutorialgateway.org/python/'.split('/') print("After Splitting String 7 = ", Str7)

Next we tried to call the String split function without using any of the arguments.

Str8 = 'Learn Python Programming Tutorial Gateway'

Str9 = Str8.split()

print("After Splitting String 8 = ", Str9)

From the Output you can observe that, it is splitting the string based on empty space because that is the default argument of string split function

Python Split String Example 2

The following set of examples will help you understand the advanced String Split in Python Programming Language. Here we will only Pass either two argument or No argument to the split function

PYTHON CODE

# Python Split String Example

# Split function with No arguments

Str1 = 'Learn Python Programming Tutorial Gateway'

Str2 = Str1.split()

print("After Splitting String 1 = ", Str2)

# Split function with Two arguments

Str3 = 'India, China, Japan, USA, UK, Australia, Canada'

Str4 = Str3.split(',', 1)

print("After Splitting String 1 = ", Str4)

Str5 = Str3.split(',', 3)

print("After Splitting String 2 = ", Str5)

Str6 = Str3.split(',', 5)

print("After Splitting String 3 = ", Str6)

OUTPUT

ANALYSIS

First we declared a String variable Str3 and assigned corresponding value using following statement

1	Str3 = 'India, China, Japan, USA, UK, Australia, Canada'

Following statement will split the Str1 string based on the separator we specified (i.e, ‘,’) and prints the output. Here the second argument will restrict the split function to split one word only.

1 2	Str4 = Str3.split(',', 1) print("After Splitting String 1 = ", Str4)

1 2	Str5 = Str3.split(',', 3) print("After Splitting String 2 = ", Str5)
