print python time index of list code example

Example 1: python return first list element that contains substring

# Example usage:
your_list = ['The answer to', 'the ultimate question', 'of life', 
     'the universe', 'and everything', 'is 42']

[idx for idx, elem in enumerate(your_list) if 'universe' in elem][0]
--> 3 # The 0-based index of the first list element containing "universe"

Example 2: 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
