As we know that Python’s built-in input() function always returns a str(string) class object. So for taking integer input we have to type cast those inputs into integers by using Python built-in int() function. Let us see the examples: Example 1: Python3
Output: 100 Example 2: Python3
Output: 10 Example 3: Python3
Output: 10 20 30 40 50 60 70 array: ['10', '20', '30', '40', '50', '60', '70'] 10 20 30 40 50 60 70 array: [10, 20, 30, 40, 50, 60, 70] Example 4: Python3
Output: Enter the size of list : 4 Enter the integer elements of list(Space-Separated): 6 3 9 10 The list is: [6, 3, 9, 10] Now, you know how to print something on the screen and not just that, you also know about the different data types available in Python and how to use them. Let’s move forward with this chapter and learn a new Python concept. Till now, we have assigned values to variables in the code. However, there can be times when we want the user to enter the value which has to be assigned to a variable. Take an example of a calculator in which the user enters the values to be added or subtracted.
The statement in the above code will read the value entered by the user (xyz) and will assign it to the variable We can also print a message on the screen while asking the user for input by passing that message to the name = input("What is your name >>>") Output In this example, the message
“What is your name >>>” will get printed on the screen and the value entered by the user after that will be assigned to the variable Let’s look at some other examples. print("Enter your name") x = input() y = input("age >>>") #age>>> will be printed before input print("Your name is",x,"and","and your age is",y) Output Enter your name print("Enter your wish") wish = input() print("May your wish come true!") Output Enter your wish What does input() do?x = input(">>>") print(x) Output If the user enters 10, then the first statement is equivalent to We gave 10 to
Taking String Input in PythonBy default, any input entered by the user is of type string. num = input() print(type(num)) Output As you can see, the user entered a number 10 as input but its type is str. Therefore, any input entered by the user is always read as string. Taking Integer Input in PythonWe just saw that input is always read as a string. So what if we want to read an integer? We can do this by converting the string input to int using the x = int(input("Enter an integer >>>")) print ("You have entered", x) Output Enter an integer <<<12
In the above example, we are taking the input from the
user as a string with the We can also break the above example in one more step to understand better. x = input("Enter an integer >>>") y = int(x) print("You have entered", y) Output Enter an integer <<<12 Here,
we passed 12. Thus, Taking Float (Decimals) Input in PythonSimilar to taking input of integers, we can use x = float(input()) print(x) print(type(x)) Output 12.32 It is similar to taking input of integers. We entered 12.32 to Let your computer do some maths for youimport math print(math.sin(30)) print(math.cos(10)) print(math.pow(2,3)) Output -0.9880316240928618
We have imported 'math' and these functions are provided by it, so 'math.sin()' can be understood as the sin() function from the 'math' directory. Checkout python's official documentation for more functions available in math. To learn from simple videos, you can always look at our Python video course on CodesDope Pro. It has over 500 practice questions and over 20 projects. In theory, there is no big difference between theory and practice. But in practice, there is. - Yogi Berra How do you input an integer in Python?As we know that Python's built-in input() function always returns a str(string) class object. So for taking integer input we have to type cast those inputs into integers by using Python built-in int() function.
How do I input data in Python?There are two functions that can be used to read data or input from the user in python: raw_input() and input(). The results can be stored into a variable. raw_input() – It reads the input or command and returns a string. input() – Reads the input and returns a python type like list, tuple, int, etc.
How do you define an integer in Python?Int. Int, or integer, is a whole number, positive or negative, without decimals, of unlimited length.
