一个简单的答案,使用一段时间的旋转:

arr = [8, 23, 45, 12, 78]
i = 0
while i < len(arr):
    print("Item ", i + 1, " = ", arr[i])
    i += 1

出口:

Item  1  =  8
Item  2  =  23
Item  3  =  45
Item  4  =  12
Item  5  =  78

如果我要重定数 = [1, 2, 3, 4, 5] 我会

for i, num in enumerate(nums, start=1):
    print(i, num)

或得到长度为 l = len(数字)

for i in range(l):
    print(i+1, nums[i])

您可以使用此代码:

ints = [8, 23, 45, 12, 78]
index = 0

for value in (ints):
    index +=1
    print index, value

使用此代码,如果您需要在路径结束时重新设置指数值:

ints = [8, 23, 45, 12, 78]
index = 0

for value in (ints):
    index +=1
    print index, value
    if index >= len(ints)-1:
        index = 0

这就足以实现目的:

list1 = [10, 'sumit', 43.21, 'kumar', '43', 'test', 3]
for x in list1:
    print('index:', list1.index(x), 'value:', x)

很容易从 0 以外的 1 开始:

for index, item in enumerate(iterable, start=1):
   print index, item  # Used to print in python<3.x
   print(index, item) # Migrate to print() after 3.x+
   

如果列表中没有双重值:

for i in ints:
    indx = ints.index(i)
    print(i, indx)
