The Python Assignment Operators are handy for assigning the values to the declared variables. Equals (=) is the most commonly used assignment operator. For example:
i = 10
The list of available assignment operators in Python language.
| Operators | Example | Explanation |
|---|---|---|
| = | x= 25 | Value 25 is assigned to x |
| += | x += 25 | This is same as x = x + 25 |
| -= | x -= 25 | Same as x = x – 25 |
| *= | x *= 25 | This is same as x = x * 25 |
| /= | x /= 25 | Same as x = x / 25 |
| %= | x %= 25 | This is identical to x = x % 25 |
| //= | x //= 25 | Same as x = x // 25 |
| **= | x **= 25 | This is same as x = x ** 25 |
| &= | x &= 25 | This is same as x = x & 25 |
| |= | x |= 25 | This is same as x = x | 25 |
| ^= | x ^= 25 | Same as x = x ^ 25 |
| <<= | x <<= 25 | This is same as x = x << 25 |
| >>= | x >>= 25 | Same as x = x >> 25 |
Python Assignment Operators Example
For this example, We are using four variables a, Total, x, and y, and their values are 7, 21, 9, and 65. Next, we use them to show the working functionality of all the Assignment Operators.
a = 7
Total = 21
Total += a # Using +=
print("The Value of the Total after using += is: ", Total)
Total -= a # Using -=
print("The Value of the Total after using -= is: ", Total)
Total *= a # Using *=
print("The Value of the Total after using *= is: ", Total)
Total //= a # Using //=
print("The Value of the Total after using //= is: ", Total)
Total **= a # Using **=
print("The Value of the Total after using **= is: ", Total)
Total /= a # Using /=
print("The Value of the Total after using /= is: ", Total)
Total %= a # Using %=
print("The Value of the Total after using %= is: ", Total)
x = 9
y = 65
x &= y # Using &=
print("The Value of the x after using &= is: ", x)
x |= 9 # Using |=
print("The Value of the x after using |= is: ", x)
x ^= y # Using ^=
print("The Value of the x after using ^= is: ", x)
In this example program, We declared 2 integer values a Total, and we assigned values 7 and 21, respectively.
The print statements will display the output of the Total after using the Python Assignment Operators on a and Total. Let us see the functionalities of all of them.
First functionality,
Total += a # Using +=
print("The Value of the Total after using += is: ", Total)
Total += a means
Total = Total + a ⇒ 21 + 7 = 28
So, the output of the above-mentioned Python print statement will be 28
The functionality of a Second one is,
Total -= a # Using -=
print("The Value of the Total after using -= is: ", Total)
Total -= a means
Total = Total – a ⇒ 28 – 7 = 21
So, the output will be 21
Third functionality,
Total *= a # Using *=
print("The Value of the Total after using *= is: ", Total)
Total *= a means
Total = Total * a ⇒ 21 * 7 = 147
So, the output will be 147
Fourth assignment operator in Python functionality,
Total //= a # Using //=
print("The Value of the Total after using //= is: ", Total)
Total //= a means
Total = Total // a ⇒ 147 // 7 = 21
So, the output of the above-mentioned print statement will be 21
Fifth functionality,
Total **= a # Using **=
print("The Value of the Total after using **= is: ", Total)
Total **= a means
Total = Total ** a ⇒ 21*21*21 *21*21*21*21 = 1,801,088,541
So, the output of the above-mentioned print statement will be 1,801,088,541
Sixth assignment operator functionality,
Total /= a # Using /=
>>> print("The Value of the Total after using /= is: ", Total)
Total /= a means
Total= Total/ a ⇒ 1,801,088,541 / 7 = 257,298,363
So, the output of Total /= a will be 257,298,363
The functionality of a Seventh assignment operator in python is
Total %= a # Using %=
print("The Value of the Total after using %= is: ", Total)
Total %= a means
Total = Total % a ⇒257,298,363 % 7 = 0 (because Remainder of 257,298,363 /7 is = 0)
In the next line, We declared 2 integer values x y, and we assigned values 9 and 65, respectively.
x = 9 y = 65
Eighth assignment operator functionality,
x &= y # Using &=
print("The Value of the x after using &= is: ", x)
x &= y means
x = x&y ⇒ 9 & 65
⇒ 00001001 & 01000001 = 00000001 ⇒ 1
So, the output of x &= y is 1. Please refer Bitwise
Ninth one’s functionality,
x |= 9 # Using |=
print("The Value of the x after using |= is: ", x)
x |= 9 means x | 9 ⇒ 1 | 9
⇒ 00000001 | 00001001 = 00001001 ⇒ 9
So, the output will be 9
The functionality of a Tenth assignment operator in Python,
x ^= y # Using ^=
>>> print("The Value of the x after using ^= is: ", x)
x ^= y means
x = x ^ y ⇒ 9 ^65
⇒ 00001001 ^ 01000001 = 01001000 ⇒ 72
So, the output will be 72.
