def creazyRead(): ''''' with open("e:creazy.txt","r") as cr: for line in cr: print line ''' ms = open("e:creazy.txt") for line in ms: with open("e:monday.txt","a") as mon: mon.write(line) |
另一种方法使用readlines实现：

def creazyRead(): ms = open("e:creazy.txt") for line in ms.readlines(): with open("e:monday.txt","a") as mon: mon.write(line) |
