Python has a very useful inbuilt function, which is called enumerate(). This is needed whenever you need the numbering of a certain element. Suppose you have a text file or a list or element which contains multiple elements , the enumerate() function can be used to numbering them. As in the example below -I have a file which has multiple lines of text. I can number each line by using this simple technique -Here we open a file and read the lines but while reading we can count the line no by using enumerate.
Also, we can enumerate lists and dictionary with this function in the same way.
abc=open('abc.txt')
for count,text in enumerate(abc.readlines()):
print (count,text)
