In this tutorial, we will learn about python enumerate() method and its uses.
WHAT IS PYTHON ENUMERATE() METHOD?
The enumerate() method adds a counter to an iterable and returns its enumerated object.
The syntax of enumerate() is:
enumerate(iterable, start=0)
PYTHON ENUMERATE() PARAMETERS
enumerate() method takes two parameters:
iterable – A sequence, an iterator, or an object that supports iteration.
start – Starts counting from this number. If start is omitted, 0 is taken as a start. This is an Optional.
Let’s check some examples of python enumerate()
Example 1: How Enumerate() Works In Python?
cars = [‘BMW’,’Audi’,’Toyota’]
enumerateCars = enumerate(cars)
print(type(enumerateCars))
print(list(enumerateCars))
# changing the default counter
enumerateCars = enumerate(cars, 10)
print(list(enumerateCars))
The output will be as follows.
<class ‘enumerate’=””>
[(0, ‘BMW’), (1, ‘Audi’), (2, ‘Toyota’)]
[(10, ‘BMW’), (11, ‘Audi’), (12, ‘Toyota’)]</class>
Example 2: Looping with an Enumerate object.
cars = [‘BMW’,’Audi’,’Toyota’]
for item in enumerate(cars):
print(item)
Output:
(0, ‘BMW’)
(1, ‘Audi’)
(2, ‘Toyota’)
RULES OF ENUMERATE()
The enumerate() method takes a collection(e.g. a list) and returns it as an enumerate object.
The enumerate() method adds a counter as the key of the enumerate object.
