1. 首先建立文件如下,使用utf-8编码:打开原txt-->输入文本-->另存为utf-8-->覆盖原txt 【将文件设置为utf-8编码格式】 2. UnicodeDecodeError: 'gbk' codec can't decode byte 0xa4 in position 54: illegal multibyte sequence 出现这个错误时,一般是因为encoding未设置造成,例如: f1 = open(path, 'r'...
with io.open(path,'w',encoding='utf-8') as f: f.write(unicode("\xEF\xBB\xBF", "utf-8"))#函数将\xEF\xBB\xBF写到文件开头,指示文件为UTF-8编码。 f.write(u'这是中文') with open(r'd:\aaa.txt','r') as ff: a= unicode(ff.read(),'utf-8')#编码为UTF-8输出 print a...

遇到这种情况, open() 函数还接收一个 errors 参数,默认是 errors=None 表示如果遇到编码错误后如何处理。最简单的方式是直接忽略 代码语言:javascript 复制 f=open('test/utf8.txt','r',encoding='utf-8',errors='ignore') 划重点!!!墙裂建议使用with open() ...
1.readline,优点:节省内存,不需要一次性把文件内容放入内存中缺点:速度相对较慢f = open("ip.txt", "r", encoding="utf-8") ret = f.readline() while ret: print(ret, end='') ret = f.readline() f.close() 2.readlines,一次性读取所有行,内存消耗过大f = open("ip.txt", "r", encoding...
