<pre name="code" class="python">creazy.txt文件有4G，逐行读取其内容并写入monday.txt文件里。
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)
