检查用户在Python中输入的文件夹是否存在

Question

我正在尝试在True循环中执行一系列检查以查看文件夹是否存在或用户错误。在我的文件夹中，我有两个文件夹A和B.我将要求用户输入文件夹名称。

from os.path import exists 

folder1_2 = input('Enter folder name: ') 
i = (folder1, folder2) 

while True: 
    i = raw_input() 
    does_it_exist = os.path.exists(i) # True/False 
    if does_it_exist == False: 
     print("The folder does not exist")    
     continue 
    if os.listdir(".") == False: 
      print("folder not found") 
     continue 
    if i('A', 'B') == False: 
      print("not the same folder or user error") 
     continue 
    break 
print("All tests passed successfully!") 

return [folder1_2] 

Answer 1

while True: 
    f1 = input("Folder1?") #asking user for input 
    f2 = input("Folder2?") 
    if not os.path.exists(f1) or not os.path.exists(f2): 
     print("some error message") 
     continue 
    if not os.path.isdir(f1) or not os.path.isdir(f2): 
     print("another error message") 
     continue 
    if (f1 == f2): #are these folders the same 
     print("one more error message") 
     continue 
    break 
print("all tests passed successfully!") 

我希望这有助于。
