python输入文件路径,Python-文件路径输入

this code works fine when I put the path of the file myself. but when I want to get it from users raw_input() it doesn't work. what can I do?

import string

import random

print "enter number between 6 and 20"

n = raw_input()

print "enter pathway of file"

p = raw_input()

print "creating a new text file"

new_file = open(p, "w") #the error on this line

m = int(n)

print random.choice(string.ascii_lowercase)

for i in range(0,m):

for j in range(0,m):

new_file.write(random.choice(string.ascii_lowercase))

new_file.write("\n")

From the error message you quoted, it looks like you're adding doublequotes to your user input and escaping the backslashes. Don't do that.

Instead of entering

"c:\\Users \\USER\\Desktop\\bar.txt"

at the prompt, enter:

C:\users\USER\Desktop\bar.txt
