‘Boolean Not is equal to !=‘?
Anyone has the same idea for this question? See below Please. Line 1 & Line 3 are False. print(not 1 == 1) print(not 1 > 7) print(1!=1)

What do you not understand ?
1. 1==1 outputs True, so not(1==1) will output False
2. Same concept
3. != tests if two things have different values, the statement tests if 1 is not equal to 1, since they're equal, the output is again False

not this is a negation while ==, !=, >= etc are the comparisons of 2 values‼️🤔

No, != and not are not the same.
not is used to negate a boolean,
while != is used to compare 2 values as not equal.
not x is used to convert x to True, when x is False, and False, when x is True.
x != y is True, when x is not equal to y, otherwise False.
not x == y would equal x != y, but in place of x == y there would be any kinds of comparisons, even comparisons, that don't have second operand y, like x != y does.
