python open找不到文件怎么办?
python open找不到文件的解决办法:
在python和很多程序语言中"\"转义符号,要想输出\有两种方法,一是多加一个\写成\\ ,一是在字符串前加一个r,提示解释器按原始字符处理
解决方法1代码:
try: source=open('D:\eclipse-workspace\AcrSoftware\data\\filename.txt','r',encoding='utf-8') except IOError: print('Error:没有找到 文件或读取文件失败')
解决方法2代码:
try: source=open(r'D:\eclipse-workspace\AcrSoftware\data\filename.txt','r',encoding='utf-8') except IOError: print('Error:没有找到 文件或读取文件失败')
