os.rename 失败，出现 [Errno 2] 没有那个文件或目录

Question

在 python 中使用 os.rename 并得到“[Errno 2] 没有那个文件或目录”

完整代码：

import os
from string import digits # digits are one of 0123456789

path = "/Users/xxx/Documents/version-control/secret-msg/prank/"
l = os.listdir(path) # returns list of files in folder
for o in l: #o for 'original'
    c = o.lstrip(digits) # c for 'clean', without leading digits; lstrip = left strip - so left strip any digit
    if (o != c):
        os.rename (o, c) #rename original filename to clean one
        print o + '-> ' + c # for debug only

Answer 1

listdir returns 文件列表 没有路径

所以，你应该这样做：

import os
import os.path
from string import digits # digits are one of 0123456789

path = "/Users/xxx/Documents/version-control/secret-msg/prank/"
l = os.listdir(path) # returns list of files in folder
for o in l: #o for 'original'
    c = o.lstrip(digits) # c for 'clean', without leading digits; lstrip = left strip - so left strip any digit
    if (o != c):
        os.rename (os.path.join(path, o),
                   os.path.join(path, c) #rename original filename to clean one
        print o + '-> ' + c # for debug only

我们使用os.path.join加入文件名的路径。
