#python – ValueError: invalid literal for int() with base 10

python – ValueError: invalid literal for int() with base 10

>>> int(55063.000000) Traceback (most recent call last):  File <stdin>, line 1, in <module> ValueError: invalid literal for int() with base 10: 55063.000000

Got me here…

>>> int(float(55063.000000)) 55063

Has to be used!

The following are totally acceptable in python:

passing a string representation of an integer into int

passing a string representation of a float into float

passing a string representation of an integer into float

passing a float into int

passing an integer into float

But you get a ValueError if you pass a string representation of a float into int, or a string representation of anything but an integer (including empty string). If you do want to pass a string representation of a float to an int, as @katyhuff points out above, you can convert to a float first, then to an integer:

>>> int(5)

JUST HAD ANOTHER MOMENT

>be me >trying to convert a string into a number. the string input is 2.5E-06 (which is 2.5x10^-6 in scientific notation). the reason to do this is because you can’t do math on strings. python treats them as words unless you convert them to numbers >function int() converts string to integer >for example if you type in “4″ as a string it will convert it to the integer 4 so that you can do math on it >>>cT = int(2.5E-06) >get “ValueError: invalid literal for int() with base 10″ >spend 3 minutes going Huh????????? >realize I cannot convert 2.5E-06 to an integer because decimals are not integers >owned by basic math once again

Just had the most epic python fail moment of my life
