Python create a file in a specific directory

Question

I'm trying to create a file in a specific folder, but the file will create in the app's path no matter what.

path = os.getcwd()
while not os.path.exists(path + "\\testfolder"):
    os.mkdir(path + "\\testfolder")

test_folder_path = path + "\\testfolder"
test_file = open(test_folder_path + "test.txt", "w")
test_file.write("test")
test_file.close()

Answer 1

It seems you're missing a separator between the path and the file name. You could consider letting os.path.join do the heavy lifting for you:

cwd = os.getcwd()
targetPath = os.path.join(cwd, testfolder);
while not os.path.exists(targetPath):
    os.mkdir(targetPath)

targetFile = os.path.join(targetPath, 'test.txt')
testFile = open(targetFile "w")
testFile.write("test")
testFile.close()

Answer 2

您在test_folder_path变量的末尾缺少斜杠，因此创建的文件路径为cwd\\testfoldertest.txt而不是cwd\\testfolder\\test.txt
