The quotation mark shouldn't be the same.


x=int(input())
print(f'W{x*"o"}w')
#it doesn't work if the quotation mark is the same

'I am Huang Wei'

>>> f'''I am {'Huang Wei'}'''
'I am Huang Wei'

>>> f"""I am {'Huang Wei'}"""
'I am Huang Wei'

>>> f"""I am {"Huang Wei"}"""
'I am Huang Wei'

>>> f'I am {'Huang Wei'}'
  File "<stdin>", line 1
    f'I am {'Huang Wei'}'
                 ^
