When working with various sequences in Python, if we want to
shows the elements of the sequence and their subscripts, you can use the enumerate () function.
The enumerate () function is used to iterate through the elements in the sequence and their subscripts, using the following:
1. The parameter is a tuple of tuple:
For index, value in enumerate (' A ', ' B ', ' C '): ' Subscript , Element ' ' print (index,value)
2. The parameter is a list of lists:
For index, value in enumerate ([1, 2, 3]): ' subscript, Element ' ' print (index, value)
3. The parameter is a string of strings:
For index, value in enumerate (' abc '): ' subscript, Element ' ' print (index, value)
4. The parameter is a dictionary dict:
For index, value in enumerate ({' A ': 1, ' B ': 2}): ' subscript (dictionary unordered), element (key value) ' print (index, value)
