which index python code example

Example 1: python find index of first matching element in a list

# Basic syntax:
list.index(element, start, end) 
# Where:
#	- Element is the item you're looking for in the list
# 	- Start is optional, and is the list index you want to start at
#	- End is option, and is the list index you want to stop searching at

# Note, Python is 0-indexed

# Example usage:
my_list = [1, 2, 3, 4, 5, 6, 7, 8, 42, 9, 10]
my_list.index(42)
--> 8

Example 2: python index method

my_string = "Hello World!"

my_string.index("l") # outputs 2
# this method only outputs the index of the first "l" value in the string/list

Example 3: how to index python

#you can index in a string like:
string='cupcake'
string[0]#returns 'c'
#you can index in a list like:
list = ['red', 'blue', 'green']
list[0]#returns 'red'
list[0][0]#returns[0] of 'red' wich is r

Example 4: index of python

# Python is a 0-based indexing language, meanign all indices start from 0
list1 = ["Python", "Is", "A", "0", "Based", "Indexing", "language"]
print(list1[0]) # Prints Python.... the element on index 0, 1 in human counting
