f2 = open(path, 'r', encoding='utf-8') a = f2.read() #read()一次读取全部内容,数据量很大时建议使用readline或者read(1024)等,1024表示字节数 print(a) f2.close() # --- f3 = open(path, 'r', encoding='utf-8') a = f3.read(4) #数据量很大时建议使用readline或者read(size)等,size...
open('test.txt','r',encoding='utf-8') 1. 2. 其中的编码模式可以不写,windows的操作系统默认编码为gbk,当内容有中文时,需要使用utf8编码。 但一般情况我们使用上下文管理语句with,这种方式可以自动管理资源,打开文件后如果忘记关闭文件会自动关闭文件: #with open('文件名',‘访问模式’,encoding='编码模式'...
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 f = open('test/utf8.txt','r',encoding='utf-8',errors='ignore') 划重点!!!墙裂建议使用with open() 划重点!!!墙裂建议使用with open() 划重点!!!墙裂建议使用with open() o...

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...
I think it is easy to replicate in any Linux if you create a path with the same name, so I include again the LOG content after having done the test in a very short path but with UTF8 characters in it (not in the filename). ⚙️ Getting saveImageAs from localStorage: png ⚙...
