This function takes any data type and converts it into a string, including integers. You have to put int() function around the input function. In this case, we see how can we convert a string to an integer in the following order: Using Inbuilt Data Types; Conventional Way . We can do this by converting the string input to int using the int() function. All the values in Python are called "objects". The upper example is no restrictions on input type data. in1 = int(input('Enter First number : ')) in2 = int(input('Enter Second number : ')) sum = in1 + in2 print(sum) I am having problems with how to parse the string and integer when they occur on the same line. Here are some examples. After writing the above code (python check if user input is a number or string), Ones you will print then the output will appear as an “ Enter the number: 22 User input is number ”. In a simple word, the program can read the line form console, which entered by users. Where in this program content reading from console and print with the sentence. Whatever you enter as input, the input function converts it into a string. The data entered by the user will be in the string format. Sometimes you will need to retrieve numbers. Sometimes you will need to retrieve numbers. You have to put int() function around the input function.
