如果此解決方案不存在，我正在嘗試創建一個 for 回圈，該回圈在創建檔案夾時瀏覽特定目錄中的檔案。這是代碼：
import ftputil
host=ftputil.FTPHost('x.x.x.x',"x","x") #connecting to the ftp server
mypathexist='./CameraOld' (he is here: /opt/Camera/CameraOld
mypath = '.' #it put you in /opt/Camera (it's the default path configured)
host.chdir(mypath)
files = host.listdir(host.curdir)
for f in files: #i browse the files in my folders
if f==mypathexist: #if a file is named CameraOld (it's a folder)
isExist=True
break
else: isExist=False #if 0 file are named like it
print(isExist)
if isExist==False: #if the file doesn't exist
host.mkdir(mypathexist) #create the folder
else:
print("ok")
問題是isExist總是假的，所以腳本嘗試創建一個已經創建的檔案夾。我不明白為什么。
這是輸出：
False #it's the print(isExist)

uj5u.com熱心網友回復：
我敢打賭你mypathexist是不正確的。或者相反，您的檔案串列不會在您假設的條件下保存字串。
用手看看你的情況。f在你的回圈中列印出來。這是你所期望的嗎？
最后，Python 只是在比較字串。
