How to Find the Length of a List in Python
Records are one of the most ordinarily utilized information types in Python and are utilized to store assortments of things of a similar sort.
This article tells the best way to discover the length of a rundown.
len() Function
Python has an underlying capacity len() that profits the length of a given article. The item can be a rundown , tuple, string, word reference, and so on.

len(list)
The capacity acknowledges just a single contention. The returned esteem is a whole number that is the quantity of components in the rundown.

counter = 0
for capital in capitals:
counter = counter + 1
print("The list has {0} elements.".format(counter))
Output
The list has 4 elements.
This strategy isn't very Pythonic. You ought to consistently favor utilizing the len() work.
Conclusion
To discover the length of a rundown in Python list, utilize the len() work.
On the off chance that you have any inquiries or criticism, don't hesitate to leave a remark.
