python – 将目录路径作为用户输入的正确方法是什么？

下面是我尝试用来将目录路径作为用户的“原始输入”的代码片段.从用户输入后,我收到以下错误：

Traceback (most recent call last):
  File "C:\Users\larece.johnson\Desktop\Python Programs\Hello World 2", line 14, in <module>
    f = open(str,"r+")                                     #I open the text file here which the user gave me
IOError: [Errno 2] No such file or directory: 'C:/Users/larece.johnson/Desktop/Python Programs/BostonLog.log.2014-04-01'

忽略我在下面所做的,是否有一种特殊的方式我应该从用户那里获取路径,以便Python接受它？

例如,我正在寻找的目录和文件是

C:/Users/larece.johnson/Desktop/Python Programs/BostonLog.log.2014-04-01

import re     #this library is used so that I can use the "search" function
import os     #this is needed for using directory paths and manipulating them 

str =""       #initializing string variable for raw data input

#print os.getcwd()
#f = open("C:/Users/larece.johnson/Desktop/BostonLog.log.2014-04-02.log","r+")

str = raw_input("Enter the name of your text file - please use / backslash when typing in directory path: ");  #User will enter the name of text file for me

f = open(str,"r+")

解决方法:

我想你应该尝试类似的东西：

import sys
import os

user_input = raw_input("Enter the path of your file: ")

assert os.path.exists(user_input), "I did not find the file at, "+str(user_input)
f = open(user_input,'r+')
print("Hooray we found your file!")
#stuff you do with the file goes here
f.close()
