Answer 1

You may need to consider the newline character:

    pattern='}'
    f = open('input.py', 'r')
    g = open('tempo.py', 'w')
    l=f.readlines()
    f.close()
    for ind in range(len(l)):
        if pattern in l[ind]:
            l[ind]= "}" + l[ind]
            l[ind] = l[ind].replace("}\n","\n")
    for field in l:
        g.write(field)
    g.close()

print('Done')

note: if your line break is windows-like then you may need to do replace ("}\r\n","\r\n")
