如何在python 3.x中打印用户输入

Question

如何以以下格式在python 3.x中打印以下行。

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：-

How old are you?
35
How tall are you ?
2
How much do you weigh?
23

所以，您今年％x岁，身高％x英尺，体重％x kg。

  

回溯（最近通话最近一次）：“ C：/ Narendra / 8th July Ethans”   “ Python Batch / Exercises / Python3 / ex11.py”，第8行，在       print（“所以，您％x岁，％x ft高，％x kg磅。”）％（年龄，身高，体重）TypeError：％不支持的操作数类型：   'NoneType'和'tuple'

Answer 1

如果您使用的是Python> = 3.6，请使用f-string

例如：

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.")

或str.format

例如：

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

Answer 2

格式运算符%对字符串起作用，而不对整个print函数起作用，该函数始终返回None。另外，您需要使用诸如%s之类的规范来指定占位符的格式。

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

Answer 3

我会这样使用.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))
