Python 为什么每次我尝试使用F字符串时，我的代码都不起作用

我知道它非常基本，这是我第一天编码，但我太迷路了 谢谢 xd

您在打印语句末尾忘记了

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year} 16.")

输出

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year}.")

age = 17
age_last_year = age - 1
print("last year it was {}.".format(age_last_year))

或者您可以使用格式

输出

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year}.")

age = 17
age_last_year = age - 1
print("last year it was {}.".format(age_last_year))

你忘了打印对账单的末尾

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year} 16.")

输出

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year}.")

age = 17
age_last_year = age - 1
print("last year it was {}.".format(age_last_year))

或者您可以使用格式

输出

age = 17
age_last_year = age - 1
print(f"last year it was {age_last_year}.")

age = 17
age_last_year = age - 1
print("last year it was {}.".format(age_last_year))
