Adds a counter to an iterable
Usage
The enumerate() function adds a counter to an iterable and returns it as an enumerate object.
By default, enumerate() starts counting at 0 but if you add a second argument start, it’ll start from that number instead.
Syntax
enumerate(iterable,start)
| Parameter | Condition | Description |
| iterable | Required | An iterable (e.g. list, tuple, string etc.) |
| start | Optional | A number to start counting from. Default is 0. |
Basic Example
# Create a list that can be enumerated
L = ['red', 'green', 'blue']
x = list(enumerate(L))
print(x)
# Prints [(0, 'red'), (1, 'green'), (2, 'blue')]Specify Different Start
By default, enumerate() starts counting at 0 but if you add a second argument start, it’ll start from that number instead.
# Start counter from 10
L = ['red', 'green', 'blue']
x = list(enumerate(L, 10))
print(x)
# Prints [(10, 'red'), (11, 'green'), (12, 'blue')]Iterate Enumerate Object
When you iterate an enumerate object, you get a tuple containing (counter, item)
L = ['red', 'green', 'blue']
for pair in enumerate(L):
print(pair)
# Prints (0, 'red')
# Prints (1, 'green')
# Prints (2, 'blue')You can unpack the tuple into multiple variables as well.
L = ['red', 'green', 'blue']
for index, item in enumerate(L):
print(index, item)
# Prints 0 red
# Prints 1 green
# Prints 2 blue
