Question

我对python很新。当我做fileofname = "a2.txt" 那么我可以毫无问题地运行我的代码但是，当我fileofname = raw_input("enter the file name:")时然后我键入“a2.txt” 它引发了"UnboundLocalError: local variable 'line' referenced before assignment"

有人能帮帮我吗？

Answer 1

fileofname = raw_input("enter the file name:")
fileObject = open(fileofname, 'r')
for line in fileObject:
    print line

Answer 2

我假设您需要阅读CSV文件

import csv
import os

ifilename = raw_input('Enter a file name: ')
ifile  = open(ifilename, "rb")
reader = csv.reader(ifile)
for row in reader:
     .......
     .........
     ..........

如果您需要阅读txt文件：

import os

print "Enter a file name:",
filename = raw_input()

OR

filename = raw_input('Enter a file name: ')
