Enumerate function Description:

function Syntax: Enumerate (the value of the object that can be traversed, starting with the index number). Enumerate (sequence, [start=0])

Function: Sequence data and data subscript are listed separately in the sequence sequence starting with start.

That is, for a data object that can be traversed (such as a list, tuple, or string), enumerate combines the data object into an index sequence, listing both the data and the data subscript.

To illustrate:

1.

1 name=["a","b","C", " D " ]2 for in Enumerate (name):3     Print (i)
View Code

The result is:

' a ' ('b') ('c' ) (' D ')

Get a few tuples.

2.

1 name=["a","b","C", " D " ]23 for in Enumerate (name):45      Print(index,i)
View Code

The result is:

0 A1 b2 c3 D

This is the reason why you should add index.

3. The start value of any defined index number:

1 name=["a","b","C", " D " ]2 for in enumerate (name,1):3     Print (Index,i)
View Code

The result is:

1 a2 b3 c4 D
