我们可以使用Path对象的exists()方法来判断文件是否存在,如果不存在则使用touch()方法创建文件。 frompathlibimportPathdefcreate_file(file_path):# 创建Path对象path=Path(file_path)# 判断文件是否存在ifnotpath.exists():# 创建文件path.touch()print(f"文件{file_path}创建成功!")else:print(f"文件{file_path...
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="test.txt"create_fi...
'''Create the new file if not exists andsave the data'''ifnot os.path.exists(datapath):os.makedirs(datapath)if __name__=='__main__':create_path_if_not_exists('model/model1/XGBoost/version_1')运行上面的文件，可以看到嵌套文件‘model/model2/XGBoost/version_2’自动建成了。现在便可以将...
