【问题描述】:
我需要指定文件路径来对从 API 检索到的 JSON 文件进行排序。我有一个保存和加载文件的类模块
import os
import json
class Directory:
def __init__(self):
self.working_dir = os.path.dirname(__file__) #Get's the current working directory
def mkdir(self, *path):
"""Creates folder in the same level as the working directory folder
Args:
*args: path to folder that is to be created
"""
target_dir = os.path.join(self.working_dir, *path)
try:
if os.path.exists(target_dir) == True:
print(target_dir, 'exists')
else:
os.mkdir(os.path.join(self.working_dir, *path))
print(os.path.join(self.working_dir, *path), 'succesfully created')
except OSError as e:
print(folder,'coult not be created', e)
def check_if_file_exist(self, *path):
if os.path.exists(os.path.join(self.working_dir, *path)):
return True
else:
return False
def save_json(self, filename, content, *path):
"""save dictionarirys to .json files
Args:
file (str): The name of the file that is to be saved in .json format
filename (dict): The dictionary that is to be wrote to the .json file
folder (str): The folder name in the target directory
"""
target_dir = os.path.join(self.working_dir, *path)
file_dir = os.path.join(self.working_dir, target_dir, filename)
with open(file_dir + '.json', "w") as f:
#pretty prints and writes the same to the json file
f.write(json.dumps(content, indent=4, sort_keys=False))
但是,例如,当必须指定文件路径时,它通常会导致非常长的行。
#EXAMPLE
filename = self.league + '_' + year + '_' + 'fixturestats'
self.dir.save_json(filename, stats, '..', 'json', 'params', 'stats')
path = '/'.join(('..', 'json', 'params'))
#OTHER EXAMPLE
league_season_info = self.dir.load_json('season_params.json', '..', 'json', 'params')
我想知道当拥有一个相对于工作目录具有相当静态文件夹的存储库时,最佳实践是什么。我的所有模块现在都已构建以创建存储库中所需的文件夹(如果它们不存在),因此我可以指望在加载或保存文件时路径存在。
