为什么我的python程序不能从命令行运行？

Question

This is my code, in TestHash.py, and it won't compile. When I type python TestHash.py nothing prints on the command line.

#import Hash.py
from Hash import *


def testHash(radix, modulus, fName):
    print("Using radix " + str(radix) + " and modulus " + str(modulus) + ".")
    print("  Input  |  hash value")
    file = open(fName)
    for line in file:
        for word in line.strip().split(' '):
            if (word != ''):
                print('{0:10s} {1:8d}'.format(word, hash(word, radix, modulus)))

Answer 1

If this is your whole program, then the program is actually running. It does not seem to run because everything is inside a function. The function is not automatically run - you need to call it to run it.

To call the function add this line to the end of your code:

testHash(radix, modulus, fName)

replacing radix , modulus , and fName with the proper values.
