Create False in Python

Buy Me a Coffee

*Memo:

  • My post explains how to create True.

<bool()>:

print(bool(False)) # bool print(bool(None)) # None print(bool(0)) # int print(bool(0.0)) # float print(bool(0.0+0.0j)) # complex print(bool([])) # Empty list print(bool(())) # Empty tuple print(bool(set())) # Empty set print(bool(frozenset([]))) # Empty frozenset print(bool({})) # Empty dict print(bool('')) # Empty str print(bool(b'')) # Empty bytes print(bool(bytearray(b''))) # Empty bytearray print(bool(range(0))) # Empty range # False

<not>:

print(not True) # bool print(not 1) # int print(not -1) # int print(not 1.0) # float print(not -1.0) # float print(not float('nan')) # float('nan') print(not float('-nan')) # float('-nan') print(not float('inf')) # float('inf') print(not float('-inf')) # float('-inf') print(not 1.0+1.0j) # complex print(not -1.0-1.0j) # complex print(not complex('nan+nanj')) # complex('nan+nanj') print(not complex('-nan-nanj')) # complex('-nan-nanj') print(not complex('inf+infj')) # complex('inf+infj') print(not complex('-inf-infj')) # complex('-inf-infj') print(not [0]) # list print(not [[]]) # list(Empty list) print(not (0,)) # tuple print(not ((),)) # tuple(Empty tuple) print(not {0}) # set print(not {frozenset()}) # set(Empty frozenset) print(not frozenset([0])) # frozenset print(not frozenset([frozenset([])])) # frozenset(Empty frozenset) print(not {0:0}) # dict print(not {():()}) # dict(Empty tuple:Empty tuple) print(not iter([])) # Empty iterator print(not iter([0])) # iterator print(not iter([iter([])])) # iterator(Empty iterator) print(not ' ') # str print(not b' ') # bytes print(not bytearray(b' ')) # bytearray print(not range(1)) # range # False

<Others>:

print(10 < 5) # < print(5 > 10) # > print(10 <= 5) # <= print(5 >= 10) # >= print(10 == 5) # == print(10 != 10) # != print(10 in [5]) # in print(True & False) # & print(False & True) # & print(False & False) # & print(True and False) # and print(False and True) # and print(False and False) # and print(False | False) # | print(False or False) # or print(True ^ True) # ^ print(False ^ False) # ^ v1, v2 = [10, 5] print(v1 is v2) # is v1, v2 = [10, 10] print(v1 is not v2) # is not # False
