To update this for Python-3 you can do this

"{} {}".format(True, False)

However if you want to actually format the string (e.g. add white space), you encounter Python casting the boolean into the underlying C value (i.e. an int), e.g.

>>> "{:<8} {}".format(True, False)
'1        False'

To get around this you can cast True as a string, e.g.

>>> "{:<8} {}".format(str(True), False)
'True     False'

You may also use the Formatter class of string  print   0   1   format True  False   print   0    1    format True  False   print   0 d   1 d   format True  False   print   0 f   1 f   format True  False   print   0 e   1 e   format True  False     These are the results  True False True False 1 0 1 000000 0 000000 1 000000e 00 0 000000e 00   Some of the  -format type specifiers   r   i  are not available  For details see the Format Specification Mini-Language

gt  gt  gt  print   r   r     True  False  True  False   This is not specific to boolean values -  r calls the   repr   method on the argument    s  for str  should also work

If you want True False use     s  s     True  False    because str True  is  True  and str False  is  False    or if you want 1 0 use     i  i     True  False    because int True  is 1 and int False  is 0
