python 列表推导

废话不多说，直接上代码

 

#coding=utf-8

def getitem(index, element):
    return '%d: %s' % (index, element)

def  getitem2():
    array = ['I', 'love', 'Python']
    arrayIndex = [getitem(index, element) for index, element in enumerate(array)]
    return arrayIndex

if __name__=="__main__":
    a=getitem2()
    print(a)


运行结果如下图：

F:\dev\python\python.exe F:/pyCharm/pratice/list_demo/demo_1.py
['0: I', '1: love', '2: Python']

Process finished with exit code 0
