读写文档，Python引入了with语句，自动调用close()，方法：with open(’/path/to/file’, ‘r’) as f，
并使用utf-8编码，encoding = ‘utf-8’，

# __author__ = 'lzc'
# -*- coding: UTF-8 -*-

def readfile(srcpath):
    with open(srcpath,'r',encoding = 'utf-8',) as f:
        for line in f.readlines():
            print(line.strip('\n'))


if __name__=="__main__":
    readfile("example.txt")
