Python输入()函数
Python input()函数用于获取用户输入。默认情况下,它以字符串的形式返回用户输入。
句法
input(prompt)
参数:
- 提示:一个字符串,表示输入之前的默认消息(通常是屏幕)。但是,是否有提示消息是可选的。
返回: input() 返回一个字符串对象。即使输入的值是整数,它也会将其转换为字符串。
示例1:将用户的姓名和年龄作为输入并打印出来
默认情况下,输入返回一个字符串。所以姓名和年龄将被存储为字符串。
Python
# Taking name of the user as input
# and storing it name variable
name = input("Please Enter Your Name: ")
# taking age of the user as input and
# storing in into variable age
age = input("Please Enter Your Age: ")
# printing it
print("The name of the user is {0} and his/her age is {1}".format(name, age))
Python
# Taking number 1 from user as int
num1 = int(input("Please Enter First Number: "))
# Taking number 2 from user as int
num2 = int(input("Please Enter Second Number: "))
# adding num1 and num2 and storing them in
# variable addition
addition = num1 + num2
# printing
print("The sum of the two given numbers is {} ".format(addition))
Python
# Taking list1 input from user as list
list1 = list(input("Please Enter Elements of list1: "))
# Taking list2 input from user as list
list2 = list(input("Please Enter Elements of list2: "))
# appending list2 into list1 using .append function
for i in list2:
list1.append(i)
# printing list1
print(list1)
输出:
示例 2:从用户那里获取两个整数并将它们相加。
在这个例子中,我们将研究如何从用户那里获取整数输入。要获取整数输入,我们将使用 int() 和 input()
Python
# Taking number 1 from user as int
num1 = int(input("Please Enter First Number: "))
# Taking number 2 from user as int
num2 = int(input("Please Enter Second Number: "))
# adding num1 and num2 and storing them in
# variable addition
addition = num1 + num2
# printing
print("The sum of the two given numbers is {} ".format(addition))
输出:
同样,我们可以使用 float() 来获取两个浮点数。让我们再看一个如何将列表作为输入的示例
示例 3:将两个列表作为输入并附加它们
Python
# Taking list1 input from user as list
list1 = list(input("Please Enter Elements of list1: "))
# Taking list2 input from user as list
list2 = list(input("Please Enter Elements of list2: "))
# appending list2 into list1 using .append function
for i in list2:
list1.append(i)
# printing list1
print(list1)
输出:
