Assignment operators using logical operators in Python

Question

I know I can use assignment operators with arithmetic operators in Python, for example:

x = 0x8
x |= 0x1  # x equals 9

I'd like to know if this is also possible with logical operators, for example something like:

x = 2 > 3  # False
y = 4 > 3  # True
x or= y  # x equals True

Is there something similar to that =or operation that I can use?

@bipll true, but the logical operators are not limited to int or bool types only. I can also use [] or {0+1j} — MattS

If you're certain the arguments will always be booleans, x |= y is functionally identical to your proposed x =or y statement. — Kevin

Ok, that's a reasonable requirement. Just making sure we're all on the same page :-) — Kevin

@bipli you shouldn't assume that either my operands nor the operation result is a boolean, in the example I presented in the comments my operands are a list and a dictionary, and the result is a dictionary — MattS

@scharette I'll maybe edit it later, but as the and and or operators are defined for many types, so should the answer be — MattS

what version of python are you in? python 3.6.5 can deal with x = False; x |= True, that yields True for x afterwards.

So just x = True, then? If the OP wanted to set x to a specific value (True), they wouldn't need to use any operators, would they?

well, x|=y works in the same way - maybe i don't quite understand the significance of his question, but it looks to me like op wants to have the equivalent to x += 4 instead of x = x + 4 for logical operations
