First, remove that try/except until the code is free of obvious bugs.
It's masking where the error actually occurs. Alternatively, include a
variable there, and print the stack trace yourself.
def Inchtocm(inches):
"""Returns 2.54 * inches"""
return (2.54 * float(inches_number1))
As Joel pointed out, you're using a global instead of the parameter that
was passed. Call float() on inches, not on some non-local variable.
inches = None
while True:
try:
inches_number1 = input(input("How many inches you want to convert:
"))
Calling input(input()) doesn't do any favors. It echoes the first
response, and waits for another one. The user doesn't probably realize
that he has to type the number 455 twice.
inches = float(inches_number1)
Since you're presumably getting the exception on this line, you should
print out the value you're trying to convert. You can remove the print
after it works.
print ("You got", Inchtocm(inches), "cm.")
print ("You converted", inches, "inches to cm.")
break
except ValueError:
print ("This is not a number!")
The code is incomplete and i am not getting a proper output:
How many inches you want to convert: 455
455
This is not a number!
How many inches you want to convert:
