print(i)
if i % 3 == 0:
print("cot")
elif i%5 == 0:
print("cot")
the code will output number from 1 to 100 and if the number between 1 and 100 is % by 3 or 5 it will be replace with cot,but if the number is cot the number will be put again,without the :cot
If i understand you correctly, what you are trying to do is to change the number to cot if it's divisible by 3 or 5.
So if any of those restrictions is accomplish, you need to assign 'cot' to the variable.
Like this:
i = <some number>
if i%3 == 0:
i = "cot"
elif i%5 == 0:
i = "cot"
print(i)
