syntax – What does the /= operator mean in Python?
syntax – What does the /= operator mean in Python?
Its an assignment operator shorthand for / and =.
Example:
x = 12
x /= 3
# equivalent to
x = x / 3
If you use help(/=), you can get the full amount of symbols supported by this style of syntax (including but not limited to +=, -=, and *=), which I would strongly encourage.
Its an augmented assignment operator for floating point division. Its equivalent to
x = x / 3
Per Makotas answer above, the following is provided by python 3, including the target types and operators, see https://docs.python.org/3/reference/simple_stmts.html#augmented-assignment-statements for more info:
augmented_assignment_stmt ::= augtarget augop (expression_list | yield_expression)
augtarget ::= identifier | attributeref | subscription | slicing
augop ::= += | -= | *= | @= | /= | //= | %= | **=
| >>= | <<= | &= | ^= | |=
