Python Assignment Operators

Introduction:

Welcome to the Python Assignment Operators Quiz! Test your understanding of essential operators like +=, -=, *=, and more, which empower you to perform operations and assignments in a single line. Strengthen your Python skills with practical examples and discover the efficiency of concise coding.

Python Assignment Operators

Python assignment operators are used to assign values to variables with an operation in a single statement. These operators combine the assignment (=) operator with another arithmetic or bitwise operator to perform the operation and assignment at the same time. The commonly used assignment operators in Python include +=, -=, *=, /=, //=, %=, **=, &=, |=, ^=, and <<=, and >>=. These operators help to write concise and efficient code by reducing the number of lines required to perform arithmetic or bitwise operations on variables.

Here are some examples of all Python Assignment Operators:

Addition Assignment (+=):

x = 5
x += 3 # equivalent to x = x + 3
print(x) # Output: 8

Example2:

x = 10
x += 5
print(x) # Output: 15

y = "Hello"
y += " World"
print(y) # Output: "Hello World"

Subtraction Assignment (-=):

 x = 10
   x -= 4 # equivalent to x = x - 4
   print(x) # Output: 6

Multiplication Assignment (*=):

x = 3
x *= 5 # equivalent to x = x * 5
print(x) # Output: 15

Example2:

x = 5
x *= 3
print(x) # Output: 15

y = "Hi "
y *= 3
print(y) # Output: "Hi Hi Hi "

Division Assignment (/=):

x = 10
x /= 2 # equivalent to x = x / 2
print(x) # Output: 5.0 (note that division operator always returns a float)

Floor Division Assignment (//=):

x = 10
x //= 3 # equivalent to x = x // 3
print(x) # Output: 3

Modulus Assignment (%=):

x = 10
x %= 3 # equivalent to x = x % 3
print(x) # Output: 1

Exponentiation Assignment (**=):

x = 3
x **= 4 # equivalent to x = x ** 4
print(x) # Output: 81

Bitwise AND Assignment (&=):

x = 10
x &= 3 # equivalent to x = x & 3
print(x) # Output: 2

Bitwise OR Assignment (|=):

x = 10
x |= 3 # equivalent to x = x | 3
print(x) # Output: 11

Bitwise XOR Assignment (^=):

x = 10
x ^= 3 # equivalent to x = x ^ 3
print(x) # Output: 9

Left Shift Assignment (<<=):

x = 10
x <<= 2 # equivalent to x = x << 2
print(x) # Output: 40

Right Shift Assignment (>>=):

x = 10
x >>= 2 # equivalent to x = x >> 2
print(x) # Output: 2

summary

• Python Assignment Operators are a convenient and efficient way to perform an operation and assign the result to a variable in a single statement.
• They are shorthand notations for commonly used operations like addition, subtraction, multiplication, division, modulus, exponentiation, bitwise operations, and shift operations.
• The Assignment Operators include +=, -=, *=, /=, //=, %=, **=, &=, |=, ^=, <<=, and >>=.
• Using Assignment Operators can make your code more concise and easier to read, especially when you are working with complex operations or multiple variables. However, it is important to use them carefully and make sure that the result of the operation is what you intended it to be.
