我们可以使用os.path.exists()函数来判断文件是否存在,如果不存在则创建文件。 importosdefcreate_file(file_path):# 判断文件是否存在ifnotos.path.exists(file_path):# 创建文件withopen(file_path,'w')asf:passprint(f"文件{file_path}创建成功!")else:
方法一:使用os模块 通过使用Python的os模块,我们可以轻松地判断文件是否存在,并在需要时创建文件。 importosdefcreate_file(file_path):ifnotos.path.exists(file_path):withopen(file_path,'w'):passprint(f"File{file_path}created successfully.")else:print(f"File{file_path}already exists.")file_path="...
一、单独使用os.makedirs(path,mode=0o777) import os path='d\\test' os.makedirs(path,0755) print('路径被创建') 二,循环创建 path=base_path+'\\'+"ciliylist[i]" if not os.path.e...

Why didn't this work for Python 3.7? The abstract reason is because such compiler optimizations are implementation specific (i.e. may change with version, OS, etc). I'm still figuring out what exact implementation change cause the issue, you can check out this issue for updates.▶...
