本文实例讲述了python中enumerate函数遍历元素用法。分享给大家供大家参考,具体如下:
enumerate函数用于遍历序列中的元素以及它们的下标
示例代码如下:
i = 0seq = ['one', 'two', 'three']for element in seq: print i, seq[i] i += 1#0 one#1 two#2 threeprint '============'seq = ['one', 'two', 'three']for i, element in enumerate(seq): print i, seq[i]print '============'for i,j in enumerate('abc'): print i,j#0 a#1 b#2 cprint '============'def _treatment(pos, element): return '%d: %s' %(pos, element)seq = ['one', 'two', 'three']print [_treatment(i, e1) for i, e1 in enumerate(seq)]
运行结果如下:
0 one1 two2 three============0 one1 two2 three============0 a1 b2 c============['0: one', '1: two', '2: three']
希望本文所述对大家Python程序设计有所帮助。
