PYTHON: Assignment Operators
Assignment operators are used to assign values to variables.
| = |
x = 5 |
x = 5 |
simply assigns the value making x become 5 |
| += |
x += 3 |
x = x + 3 |
This increases whatever value x was before by 3 |
| -= |
x -= 3 |
x = x - 3 |
This decreases whatever value x was before by 3 |
| *= |
x *= 3 |
x = x * 3 |
This multiplies what ever value x was before by a factor of 3 |
| /= |
x /= 3 |
x = x / 3 |
This divides what ever value x was before by a factor of 3 |
| %= |
x %= 3 |
x = x % 3 |
This assigns a new modulus to x
x = 5 (x is a number 5 - to base 10 like we are used to!)
x%=3 (here we assign the decimal number 5 to base 3)
print(x)
The outcome is the number 2 |
| //= |
x //= 3 |
x = x // 3 |
This 'floor divides' x by three - will divide by three and report the integer value - no remainder
For example:
x = 7
x=x//3
print(x)
will return 2 as 7 ÷ 3 = 2 remainder 1 or 2.333 |
| **= |
x **= 3 |
x = x ** 3 |
The raises a variable's value to the power of whatever number is after the '**' - in other words exponentiation of the variable's value.
For example:
x = 2
x=x**3
print(x)
will return 8 as 23 = 2 x 2 x 2 = 8 |
| &= |
x &= 3 |
x = x & 3 |
& is the AND Bitwise operator |
| |= |
x |= 3 |
x = x | 3 |
| is the OR Bitwise operator |
| ^= |
x ^= 3 |
x = x ^ 3 |
^ is the XOR Bitwise operator |
| >>= |
x >>= 3 |
x = x >> 3 |
>> is the fill right shift Bitwise operator |
| <<= |
x <<= 3 |
x = x << 3 |
<< is the Zero fill left shift Bitwise operator |
