But not the way you think:
>>> 0 == False
True
>>> 1 == True
True
>>> 2 == True
False
>>> 2 == False
False
0 equals False, 1 equals True, and any other integer equals neither, but
"is true in a boolean context", i. e.
>>> if 42: print("42 considered true")
...
42 considered true

In a similar way there is no string that equals True or False, but
the empty string "" is considered false in a boolean context while all other
strings are considered true:
>>> bool("")
False
>>> bool("whatever")
True
