Python 3.x 如何在Python3.x中打印用户输入

如何在Python3.x中以下面的格式打印下面的行

print ("How old are you?"),
age = input ()
print ("How tall are you ?"),
height = input ()
print ("How much do you weigh?"),
weight = input()

print("so , you're % year old, % ft tall and % kg heavy.")% (age,height,weight)

错误：- 那么，你是%x岁、%x英尺高、%x千克重

回溯（最近一次调用）：文件“C:/Narendra/Ethans 7月8日 Python批处理/Exercises/Python3/ex11.py”，第8行，在 打印（“因此，您是%x岁、%x英尺高、%x千克重。”）%（年龄、身高、体重）类型错误：不支持%的操作数类型： “非类型”和“元组”

格式运算符

%

处理字符串，而不是整个

print

函数，该函数始终返回

None

。此外，还需要使用规范（如

%s

）指定占位符的格式

print("so , you're %s year old, %s ft tall and %s kg heavy." % (age,height,weight))

如果您使用的是Python>=3.6：请使用

f-string

Ex:

age = input ("How old are you?\n");

height = input ("How tall are you ?\n");

weight = input("How much do you weigh?\n");

print(f"so , you're {age} year old, {height} ft tall and {weight} kg heavy.")

print("so , you're {0} year old, {1} ft tall and {2} kg heavy.".format(age, height, weight))

或

str.format

Ex:

age = input ("How old are you?\n");

height = input ("How tall are you ?\n");

weight = input("How much do you weigh?\n");

print(f"so , you're {age} year old, {height} ft tall and {weight} kg heavy.")

print("so , you're {0} year old, {1} ft tall and {2} kg heavy.".format(age, height, weight))

我会像这样使用.format（）函数

age = input('How old are you? ')
height = input('How tall are you? ' )
weight = input('How much do you weigh? ')

print(("so, you're {} year old, {} ft tall and {} kg heavy").format(age,height,weight))
