Question

我的命令行参数：

python SearchString.py 10 nee

参数1与长度不匹配。我该怎么处理？

错误：在string_search中输入第30行的“SearchString.py” search = temp [fieldindex] IndexError：列表索引超出范围

#!usr/bin/python
import sys

def string_search():
    '''
    This function search a string in a file through index and gives the result.

    :returns: none
    :return type: none 
    :author:XYZ   

    '''
    if len(sys.argv) != 3:
        print "Enter Two Arguments Only"
        sys.exit()

    stringsrch = sys.argv[2]
    found = False
    file_name = open("passwd", "r")

    if sys.argv[1].isdigit():
        fieldindex = int(sys.argv[1])-1
    else:
       print "Enter Integer in 1st Argument"
    sys.exit()
    #fieldindex = int(sys.argv[1])-1

   for store_file in file_name:
        temp = store_file.split(":")
        search = temp[fieldindex]

        if stringsrch in search:
            print store_file
            found = True
    if not found:
        print "No String "

string_search()

我认为代码取决于您如何使用它。 search = temp[fieldindex]。从代码中，您的fieldindex为9，因此您应该确保len(temp) > 9。或者你会得到像你所说的错误。
