python3中f"{}"与.format() 如何替换？

Question

在《笨办法学习python3》的第23页中，介绍了f"{}" 和.format() 的用法。这两个在使用中能否相互替换呢？

hilarious = False

          joke_evaluation = "Isn't that joke so funny? {} !"
          print(f"{joke_evaluation}  {hilarious}")

运行结果为：

        Isn't that joke so funny ?! False

在行代码中，能否使用f"{}" 来代替 .format() 呢？ 我试了几次，发现都不行，这个该怎么改写呀？

Answer 1

# f
hilarious = False
print(f"Isn't that joke so funny?  {hilarious}!")

#format
print("Isn't that joke so funny?  {}!".format(hilarious ))
