输入()参数:
接受单个参数。无论用户键入什么，它都将作为输入参数。
| 参数 | 描述 | 必需/可选 |
|---|---|---|
| 提示 | 写入标准输出(通常是屏幕)的字符串，不带尾随换行符 | 可选择的 |
输入()返回值
input()函数实际上是对输入字符串进行求值，并尝试将其作为 Python 代码运行，输出作为字符串返回。
| 投入 | 返回值 | | 线 | 通过移除尾部换行符来创建字符串 | | 如果电渗流 | 它会引发 EOFError 异常。 |
Python 中input()方法的示例
示例 1:输入()在 Python 中是如何工作的？
# get input from user
inputString = input()
print('The inputted string is:', inputString)
输出:
Python is interesting.
The inputted string is: Python is interesting 示例 2:通过提示获取用户输入
# get input from user
inputString = input('Enter a string:')
print('The inputted string is:', inputString)
输出:
Enter a string: Python is interesting.
The inputted string is: Python is interesting 示例 3:输入员工详细信息
# take three values from user
name = input("Enter Employee Name: ")
salary = input("Enter salary: ")
company = input("Enter Company name: ")
# Display all values on screen
print("\n")
print("Printing Employee Details")
print("Name", "Salary", "Company")
print(name, salary, company)
输出:
Enter Employee Name: Jessa
Enter salary: 8000
Enter Company name: Google
Printing Employee Details
Name Salary Company
Jessa 8000 Google 示例 4:计算两个输入整数相加的程序
# convert inout into int
first_number = int(input("Enter first number ")) sec second number "))
print("\n")
print("First Number:", first_number)
print("Second Number:", second_number)
sum1 = first_number + second_number
print("Addition of two number is: ", sum1)
输出:
Enter first number 28
Enter second number 12
First Number: 28
Second Number: 12
Addition of two number is: 40 本文链接：https://my.lmcjl.com/post/6266.html
