Look carefully at the error, and the line that it's coming up on. Firstly, you can rule out datetime, as nothing has been done with datetime except import it. Secondly, the invalid literal doesn't look like a decimal number at all; in fact, it looks to me like a flag of some sort. Try adding this above the failing line: print(sys.argv) And also, try running this at the terminal: $ file /usr/bin/env/python How are you invoking Python? The shebang looks wrong; perhaps it should be "/usr/bin/env python" (note the space where you have an additional slash), but perhaps it's not even being significant here.
