How to read two inputs separated by space in a single line?
提问by Prince Ashitaka
I want to read two input values. First value should be an integer and the second value should be a float.
我想读取两个输入值。第一个值应该是一个整数，第二个值应该是一个浮点数。
I saw Read two variables in a single line with Python, but it applies only if both the values are of same type. Do I have any other way?
我看到Read two variables in a single line with Python，但仅当两个值的类型相同时才适用。我还有什么办法吗？
Example input, first is int and second is float. The inputs should be on a single line:
示例输入，第一个是 int，第二个是 float。输入应该在一行上：
20 150.50

Like this:
像这样：
In [20]: a,b = raw_input().split()
12 12.2
In [21]: a = int(a)
Out[21]: 12
In [22]: b = float(b)
Out[22]: 12.2
You can't do this in a one-liner (or at least not without some super duper extra hackz0r skills -- or semicolons), but python is not made for one-liners.
你不能在单行（或者至少在没有一些超级骗子的额外 hackz0r 技能——或分号）中做到这一点，但 python 不是为单行写的。

One liner :)
一个班轮:)
>>> [f(i) for f,i in zip((int, float), raw_input().split())]
1 1.2
[1, 1.2]
回答by Phoris
Simpler one liner(but less secure):
更简单的单衬（但不太安全）：
map(eval, raw_input().split())

map(str,input().split())that is how you do it.
map(str,input().split())这就是你的方式。

If the input is separated by spaces " "
如果输入以空格“”分隔
a,b,c = raw_input().split(" ")
a,b,c = raw_input().split(" ")
If the input is separated by comma ','
如果输入以逗号 ',' 分隔
a,b,c = raw_input().split(",")

A,B = raw_input().split(" ")
A = int(A)
B = float(B)
print(A)
print(B)
Output

If you wish to take as many inputs as u want then following:
如果您希望获得尽可能多的输入，请执行以下操作：
x=list(map(str,input().split()))
print(x)
If you want two inputs:
如果你想要两个输入：
x,y=x,y=list(map(str,input().split()))
print(x,y)

This is good solution imho a, b = input().split().
恕我直言，这是一个很好的解决方案a, b = input().split()。
If you want to separate input with custom character you can put it in parenthesis e.g. a, b = input().split(",")
如果你想用自定义字符分隔输入，你可以把它放在括号中，例如 a, b = input().split(",")

Below snippet works for me.
下面的片段对我有用。
a, b = input().split(" ")
a_value = int(a)
b_value = int(b)
