Any thoughts on my code? It's a simple hashing code that runs from the command line.

There just appears to be a lot of condition `if` / `elif` entries in both of the main functions (`hashingmethod` and `hashcalculator`). 

```
# hashcalculator.py

import sys
import hashlib

args = len(sys.argv)

def inputVerification():
    if sys.argv[1] == "--help":
        scriptHelp()
    elif args < 5:
        print "You have failed to execute the command correctly"
        print "Please type 'hashcalculator --help' for more information"
    else:
        filename = sys.argv[2]
        hashingMethod(filename)

def scriptHelp():
    print "\n"
    print "----------------------------------------"
    print "\tWelcome to Hash Calculator"
    print "----------------------------------------"
    print "\n"
    print "--help"
    print "\n"
    print "In order to calculate the hash value of a file, your command line syntax"
    print "must be written as below:-"
    print "\n"
    print "\thashcalculator -f [file] -h [hash method]"
    print "\teg. hashcalculator -f notepad.exe -h SHA1"
    print "\n"
    print "The recognised hashing methods are MD5, SHA1, SHA224, SHA256, SHA384 and SHA512" 

def hashingMethod(filename):
    hashmethod = sys.argv[4].upper()
    if hashmethod == "MD5":
        hashCalculator(filename, "md5")
    elif hashmethod == "SHA1":
        hashCalculator(filename, "sha1")
    elif hashmethod == "SHA224":
        hashCalculator(filename, "sha224")
    elif hashmethod == "SHA256":
        hashCalculator(filename, "sha256")
    elif hashmethod == "SHA384":
        hashCalculator(filename, "sha384")
    elif hashmethod == "SHA512":
        hashCalculator(filename, "sha512")
    else:
        print "You have not entered a valid hashing method"
        print "Please review the help document"
        scriptHelp()

def hashCalculator(filename, hashmethod):
    with open(filename, 'rb') as f:
        if hashmethod == "md5":
            m = hashlib.md5()
        elif hashmethod == "sha1":
            m = hashlib.sha1()
        elif hashmethod == "sha224":
            m = hashlib.sha224()
        elif hashmethod == "sha256":
            m = hashlib.sha256()
        elif hashmethod == "sha384":
            m = hashlib.sha384()
        elif hashmethod == "sha512":
            m = hashlib.sha512()
        else:
            scriptHelp()
        while True:
            data = f.read(8192)
            if not data:
                break
            m.update(data)
        print "\n\n"
        print "The %s hash of file %s is:" % (hashmethod.upper(), filename)
        print "\n", m.hexdigest()

if __name__ == "__main__":
    inputVerification()

```
