python list 分片方法

目標

一個長度特別大的 list
需要進行分片輸出

參考代碼如下

#!/usr/bin/python
# -*- coding:utf-8 -*-


def listFragment():
    ltest = range(1, 101)
    print("ltest type is : %s" % (type(ltest)))

    print("ltest length is : %s" % (len(ltest)))

    for fragment in range(0,len(ltest),20):
        getFragment = ltest[fragment:fragment+20]
        print(getFragment)

if __name__ == '__main__':
    listFragment()

參考輸出效果如下

ltest type is : <type 'list'>
ltest length is : 100
