通过本文主要向大家介绍了python enumerate函数,python中enumerate,python enumerate,python3 enumerate,enumerate函数等相关知识,希望对您有所帮助,也希望大家支持linkedu.com www.linkedu.com
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 = 0
seq = ['one', 'two', 'three']
for element in seq:
print i, seq[i]
i += 1
#0 one
#1 two
#2 three
print '============'
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 c
print '============'
def _treatment(pos, element):
return '%d: %s' %(pos, element)
seq = ['one', 'two', 'three']
print [_treatment(i, e1) for i, e1 in enumerate(seq)]
</div>
运行结果如下：
0 one 1 two 2 three ============ 0 one 1 two 2 three ============ 0 a 1 b 2 c ============ ['0: one', '1: two', '2: three']</div>
希望本文所述对大家Python程序设计有所帮助。
