這篇文章主要介紹Python enumerate()函數(shù)實現(xiàn)索引功能的方法，文中示例代碼介紹的非常詳細，具有一定的參考價值，感興趣的小伙伴們一定要看完！

1.描述：

enumerate()函數(shù)用于將一個可遍歷的數(shù)據(jù)對象(如列表，元組，字符串)組合為一個索引序列，同時列出數(shù)據(jù)和數(shù)據(jù)索引(下標)，一般用于for循環(huán)當(dāng)中

2.語法

enumerate(sequence, [start=0])

3.參數(shù)：

• sequence：一個序列，迭代器或其他支持迭代對象
• start：可選參數(shù)，下標起始位置，默認從索引0開始

4.返回值

返回enumerate(枚舉)對象

5.實例

list1 = [10,20,30,40,"maple","yf",60]

tup1 = (100,200,300,400,"hao","qazert",600)

str1 = "1234qwertjdsa22323"

for index1,item1 in enumerate(list1):
  print("index1 = %d, item1 = %s" %(index1,item1,))

print("------------------------------")
for index2, item2 in enumerate(list1,start = 2):
  print("index2 = %d, item2 = %s" %(index2,item2,))

print("******************************")
for index3,item3 in enumerate(tup1):
  print("index3 = %d, item3 = %s" % (index3, item3,))

print("==============================")
for index4,item4 in enumerate(tup1, start = 4):
  print("index4 = %d, item4 = %s" % (index4, item4,))

print("%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%")
for index5,item5 in enumerate(str1):
  print("index4 = %d, item4 = %s" % (index5, item5,))

print("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$")
for index6,item6 in enumerate(str1,start = 6):
  print("index4 = %d, item4 = %s" % (index6, item6,))
