1.相对路径
windows '.\\'表⽰当前路径
with open(r'.\\db\\123.txt','w',encoding='utf-8') as f: f.write('abc')
2.绝对路径
2.1 直接加死绝对路径
with open('c:\\db\\123.txt','w',encoding='utf-8') as f: f.write('abc')
2.2 动态绝对路径
import os,sys
project_path = os.path.dirname(os.path.abspath(__file__)) # 获取当前⽂件路径的上⼀级⽬录file_path = project_path+r'\\db\\123.txt' # 拼接路径字符串with open(file_path,'w',encoding='utf-8') as f: f.write('abc')
