# find out indexes of element in the list

#Find out the indexes of an element in the list:
list = [10,7,9,27,10,30,40,50,75,47,66,89,10,566,100]
[i for i, x in enumerate(list) if x == 10]

Output:
[0, 4, 12]

find an index of an item in a list python

#Example List
list = ['apples', 'bannas', 'grapes']
#Use Known Entites In The List To Find The Index Of An Unknown Object
Index_Number_For_Bannas = list.index('apples')
#Print The Object
print(list[Index_Number_For_Bannas])

find index of elem list python

# Find index position of first occurrence of 'Ok' in the list 
indexPos = listOfElems.index('Ok')
 
print('First index of element "Ok" in the list : ', indexPos)
