Is this the best way to write a "loop and a half" in Python?
Define "best".
x = 1
while x:
x = int( input( "Number (enter 0 to terminate)? " ))
if x:
print( f'Square = { x**2 }' )
I'd usually write it as
while True:
x = tedious_function_call_with_sentinel()
if x == 0:
break
do_something_with(x)
...or alternatively
x = tedious_function_call_with_sentinel()
while x != 0:
do_something_with(x)
x = tedious_function_call_with_sentinel()
...or some other refactoring.
In a C-like language, one could write:
while x = int( input( "Number (enter 0 to terminate)? " ))
print( f'Square = { x**2 }' )
One could. One would richly deserve the compiler warnings one got as a
result, but one could.
