How to find the Index of an Element in a List in Python

  1. find the Index of an Element in a List in Python

    to find the Index of an Element in a List in Python just Use index().By using index() you can find the Index of an Element in a List in Python. Lets learn about of this by given below example:
    lst = [12,14,16,18,20,101] print(lst.index(20))
    Output :
    4

  2. How to find the Index of an Element in a List in Python

    to find the Index of an Element in a List in Python just Use numpy.where().By using numpy.where() you can find the Index of an Element in a List in Python. Lets learn about of this by given below example: import numpy as np lst = [12,14,12,18,20,101,12] lst = np.array(lst) result = np.where(lst == 12) print(result[0]) Output : [0 2 6]

  3. python list find index

    To find the Index of an Element in a List in Python just Use numpy.where().By using numpy.where() you can find the Index of an Element in a List in Python. Lets learn about of this by given below example: import numpy as np lst = [12,14,12,18,20,101,12] lst = np.array(lst) result = np.where(lst == 12) print(result[0]) Output : [0 2 6]

Method 1: Use index()

By using index() you can find the Index of an Element. Lets learn about of this by given below example: 

lst = [12,14,16,18,20,101]
print(lst.index(20))

Output :

4

Method 2: Use numpy.where()

By using numpy.where() you can find the Index of an Element. Lets learn about of this by given below example: 

import numpy as np
lst = [12,14,12,18,20,101,12]
lst = np.array(lst)
result = np.where(lst == 12)
print(result[0])

Output :

[0 2 6]

Method 3: Use type() operator

By using type() we can get the index of string elements. Lets learn about of this by given below example: 

list1 = ['one',2,'three',4,'five',6]
for i in list1:
    if(type(i) is str):
        print(list1.index(i))

Output :

0
2
4
