Help with identation

No Luck even after i changed as above.

You should not get TabError with that code.
Test:

tofind = '<map>'
tofind1 = '</map>'

with open('in.txt') as my_file:
    for num, line in enumerate(my_file, 1):
        if tofind in line:
            print(f'{tofind} at line: {num}')
        if tofind1 in line:
            print(f'{tofind1} at line: {num}')

Output:
<map> at line: 1
</map> at line: 5
<map> at line: 11
</map> at line: 16
