# create a list of names and marks
list1 = ['sravan', 98, 'harsha', 'jyothika',
        'deepika', 78, 90, 'ramya']
print(list1)
# iterate through list of elements
for i in list1:
 
    # check for type is str
    if(isinstance(i, str)):
     
        # display index
        print(list1.index(i))

Python – Find Index containing String in List

												
												

													
													
Given a list, the task is to write a Python Program to find the Index containing String.

													
													
												

												
												

													
													
Example:

													
													
												

												
												

													
													


Input: [‘sravan’, 98, ‘harsha’, ‘jyothika’, ‘deepika’, 78, 90, ‘ramya’]


Output: 0 2 3 4 7


Explanation: Index 0 2 3 4 7 contains only string.
