In python, The enumerate function traverses the element usage analysis, and pythonenumerate

This document describes how to use the enumerate function to traverse elements in python. We will share this with you for your reference. The details are as follows:

The enumerate function is used to traverse the elements in the sequence and Their subscript.

The sample code is as follows:

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)]

The running result is as follows:

0 one1 two2 three============0 one1 two2 three============0 a1 b2 c============['0: one', '1: two', '2: three']
