Python 用户获取多个输入

开发人员通常希望用户在一行中输入多个值或输入。在 C++/C 中，用户可以使用 scanf 在一行中获取多个输入，但在 Python 中，用户可以通过两种方法在一行中获取多个值或输入。

使用 split() 方法
使用列表理解

使用split()方法：此函数有助于从用户那里获取多个输入。它通过指定的分隔符打破给定的输入。如果未提供分隔符，则任何空格都是分隔符。通常，用户使用 split() 方法来拆分 Python 字符串，但也可以使用它来获取多个输入。

句法：

input().split(separator, maxsplit)

例子：

Python3

# Python program showing how to
# multiple input using split

# taking two inputs at a time
x, y = input("Enter two values: ").split()
print("Number of boys: ", x)
print("Number of girls: ", y)

# taking three inputs at a time
x, y, z = input("Enter three values: ").split()
print("Total number of students: ", x)
print("Number of boys is : ", y)
print("Number of girls is : ", z)

# taking two inputs at a time
a, b = input("Enter two values: ").split()
print("First number is {} and second number is {}".format(a, b))

# taking multiple inputs at a time
# and type casting using list() function
x = list(map(int, input("Enter multiple values: ").split()))
print("List of students: ", x)

输出：

Enter two values: 5 10
Number of boys:  5  
Number of girls:  10
Enter three values: 5 10 15
Total number of students:  5
Number of boys is :  10     
Number of girls is :  15    
Enter two values: 5 10
First number is 5 and second number is 10
Enter multiple values: 5 10 15 20 25
List of students:  [5, 10, 15, 20, 25]

使用**列表理解**：列表理解是一种在 Python 中定义和创建列表的优雅方式。我们可以只在一行中创建列表，就像数学语句一样。它还用于从用户获取多个输入。

例子：

Python3

# Python program showing
# how to take multiple input
# using List comprehension

# taking two input at a time
x, y = [int(x) for x in input("Enter two values: ").split()]
print("First Number is: ", x)
print("Second Number is: ", y)

# taking three input at a time
x, y, z = [int(x) for x in input("Enter three values: ").split()]
print("First Number is: ", x)
print("Second Number is: ", y)
print("Third Number is: ", z)

# taking two inputs at a time
x, y = [int(x) for x in input("Enter two values: ").split()]
print("First number is {} and second number is {}".format(x, y))

# taking multiple inputs at a time
x = [int(x) for x in input("Enter multiple values: ").split()]
print("Number of list is: ", x)

输出：

Enter two values: 5 10
First Number is:  5
Second Number is:  10
Enter three values: 5 10 15
First Number is:  5
Second Number is:  10
Third Number is:  15
Enter two values: 5 10
First number is 5 and second number is 10
Enter multiple values: 5 10 15 20 25
Number of list is:  [5, 10, 15, 20, 25]

注意：以上示例采用以空格分隔的输入。如果我们希望输入以逗号 (,) 分隔，我们可以使用以下内容：

Python3

# taking multiple inputs at a time separated by comma
x = [int(x) for x in input("Enter multiple value: ").split(",")]
print("Number of list is: ", x)
