Question

我想看看是否存在某些目录。脚本是说它不存在，但我知道它确实存在。

我认为它与以这种格式存储在列表中的字符串有关（双反斜杠）：＆＃34; \\服务器\\ PATH1 \\＆＃34 + +的env＆＃34; \\ PATH2＆＃34;

当我将路径存储到对象中时，它运行正常。例如 path =＆＃34; \\ servername \ path1 \ evv \ path2＆＃34;

import os 

x =["env1","env2","env3","env4"]
j=[]
for env in x:
    q=r"\\servername\\path1\\"+env+"\\path2"
    w=r"\\servername\\path1\\"+env+"\\path2"
    e=r"\\servername\\path1\\"+env+"\\path2"
    r=r"\\servername\\path1\\"+env+"\\path2"
    t=r"\\servername\\path1\\"+env+"\\path2"
    y=r"\\servername\\path1\\"+env+"\\path2"
    u=r"\\servername\\path1\\"+env+"\\path2"
    i=r"\\servername\\path1\\"+env+"\\path2"
    o=r"\\servername\\path1\\"+env+"\\path2"
    p=r"\\servername\\path1\\"+env+"\\path2"
    a=r"\\servername\\path1\\"+env+"\\path2"
    s=r"\\servername\\path1\\"+env+"\\path2"
    d=r"\\servername\\path1\\"+env+"\\path2"
    f=r"\\servername\\path1\\"+env+"\\path2"
    g=r"\\servername\\path1\\"+env+"\\path2"
    h=r"\\servername\\path1\\"+env+"\\path2"
    j.extend((q,w,e,r,t,y,u,i,o,p,a,s,d,f,g,h))



for path in j:
    if os.path.exists(path):
        print "It Exists"
    else:
        print "It doesnt Exist"
print j

[＆＃34; \\服务器\ PATH1 \＆＃34 + +的env＆＃34; \ PATH2＆＃34;]

需要一个for循环来将列表输出为正确的格式

for string in j:
    print string
    if os.path.exists(string):
        print "It Exists"
    else:
        print "It doesnt Exist"

Python使用for循环和列表检查目录是否存在
