Python 3's f-Strings: An Improved String Formatting Syntax (Guide) – Real Python

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

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

>>> f'I am {'Huang Wei'}'
  File "", line 1
    f'I am {'Huang Wei'}'
                 ^
SyntaxError: invalid syntax
