Assignment Operators in Python
Assignment operators are used to assigning value to a variable. The left side operand of the assignment operator is a variable and right side operand of the assignment operator is a value. This operator is used to assign the value on the right to the variable on the left
| Compound Operator | Sample Expression | Expanded Form |
|---|
| += | a+=2 | a=a+2 |
| -= | a-=6 | a=a-6 |
| *= | a*=7 | a=a*7 |
| /= | a/=4 | a=a/4 |
| %= | a%=9 | a=a%9 |
| **= | a**=3 | a=a**3 |
| //= | a//=2 | a=a//2 |
This program is using the assignment operators along with the basic arithmetic operations in python
- a = 125: This line assigns the value 125 to the variable a.
- print(a): This line prints the value of a which is 125.
- a += 5: This line uses the shorthand assignment operator += to add 5 to the current value of a and assigns the result back to a. The value of a becomes 130.
- print(a): This line prints the updated value of a which is 130.
- a -= 10: This line uses the shorthand assignment operator -= to subtract 10 from the current value of a and assigns the result back to a. The value of a becomes 120.
- print(a): This line prints the updated value of a which is 120.
- a *= 10: This line uses the shorthand assignment operator *= to multiply the current value of a by 10 and assigns the result back to a. The value of a becomes 1200.
- print(a): This line prints the updated value of a which is 1200.
- a /= 10: This line uses the shorthand assignment operator /= to divide the current value of a by 10 and assigns the result back to a. The value of a becomes 120.
- print(a): This line prints the updated value of a which is 120.
- a %= 10: This line uses the shorthand assignment operator %= to find the remainder when dividing the current value of a by 10 and assigns the result back to a. The value of a becomes 0.0.
- print(a): This line prints the updated value of a which is 0.0.
- a **=10: This line uses the shorthand assignment operator **= to raise the current value of a to the power of 10 and assigns the result back to a. The value of a becomes 0.0.
- print(a): This line prints the updated value of a which is 0.0.
- a //= 10: This line uses the shorthand assignment operator //= to divide the current value of a by 10 and assigns the result rounded down to the nearest integer back to a. The value of a becomes 0.0.
- print(a): This line prints the updated value of a which is 0.0.
