报错：[Errno 22] Invalid argument: ‘data\text.txt‘

问题解决参考

python在使用绝对路径时出现OSError: [Errno 22] Invalid argument: ‘E:\python\python扩展\text_file\pi_digits.txt

问题背景

使用with open语句时报错

[Errno 22] Invalid argument: 'data\text.txt'

原代码

with open('data\text.txt','r',encoding='GBk') as f:
    a = f.read()

解决问题

原因可能是python的解释器默认了（\）为转义字符，所以报错

• 写法1：路径前加r

# 写法1
with open(r'data\text.txt','r',encoding='GBk') as f:
    a = f.read()
 a

• 写法2：“\”变‘\’

# 写法2
with open('data\\text.txt','r',encoding='GBk') as f:
    a = f.read()
 a
