Please show your actual code - you might want to use a list comprehension. — Jan, Sep 25 '20 at 15:56
What kind of error did you faced? And please show your codes? — Adem Öztaş, Sep 25 '20 at 15:56
Please show your code [_as formatted text in the question_](/help/formatting). This allows people to copy your code into their own execution environments to test it, so they won't have to type it all from scratch. Also, it makes your code searchable so people looking for answers to the same problem can find it in the future. Welcome to Stack Overflow! — Pranav Hosangadi, Sep 25 '20 at 16:06

initializing list

array = ['a1', '2', '3', '4', '5'] 

for i in range(0, len(array)): 
    if array[i].isdigit():
        array[i] = float(array[i])

print ("Modified list is : " + str(array))

Modified list is : ['a1', 2.0, 3.0, 4.0, 5.0]
