Nowadays, several programs have dialog boxes to ask the users to provide similar or distant inputs. In Python 2, there are two different kinds of in-built functions. These functions help in reading input given by the user using keywords.<\/p>\n\n\n\n
Below, we have provided all the necessary details to answer your question- how can I read input as numbers<\/strong>. Moreover, we have provided valuable examples that help you understand each concept of the input function.<\/p>\n\n\n That is to say if the user’s input is incorrect, it will either show a syntax error or an exception in Python. For instance\u2013<\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter your name:<\/strong><\/p>\n\n\n\n 123<\/strong><\/p>\n\n\n\n Hello 123<\/strong><\/p>\n<\/div><\/div>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter number:123<\/strong><\/p>\n\n\n\n 123<\/strong><\/p>\n<\/div><\/div>\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n type of number <class ‘str’><\/strong><\/p>\n\n\n\n type of name <class ‘str’><\/strong><\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter input to test raw_input() function:0<\/strong><\/p>\n\n\n\n <type ‘str’><\/strong><\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n To sum up, the key point to remember is a small difference between Python 2 input and Python 3 input. In Python 2, the input() function automatically evaluates the input data and converts it into an integer. <\/p>\n\n\n\n However, in the case of Python 3, the input() function does not <\/em><\/strong>evaluate the user input. This means that Python 2’s raw_input() is equivalent <\/em><\/strong>to the Python3 input()_ function.<\/p>\n\n\n\n So, let’s understand it with the help of an example:<\/p>\n\n\n\n Python 2 input() function<\/strong><\/p>\n\n\n Output<\/strong><\/p>\n\n\n\n Enter a number: 5 <\/strong><\/p>\n\n\n\n (5, <type ‘int’>)<\/strong><\/p>\n<\/div><\/div>\n\n\n\n Python 2 raw_input() function<\/strong><\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter a number: 5 <\/strong><\/p>\n\n\n\n (5, <type \u2018str\u2019>)<\/strong><\/p>\n<\/div><\/div>\n\n\n\n NOTE: <\/strong>Here, you will notice that the input() function will show the data type like int, <\/em><\/strong>whereas the raw_input() shows the same data type as str. <\/em><\/strong>That is to say that raw_input does not evaluate the function and read it as it is.<\/p>\n\n\n\n Python 3 input() function<\/strong><\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter a number: 5 <\/strong><\/p>\n\n\n\n (5, <type \u2018str\u2019>)<\/strong><\/p>\n<\/div><\/div>\n\n\n\n NOTE: <\/strong>Remember that the raw_input() function is not available in Python 3.<\/p>\n\n\n\n No, it doesn’t mean that! As we have already mentioned that the raw_input does not exist in Python 3. So, the older raw_input() is replaced with the input(), and the older input is replaced. <\/p>\n\n\n\n Do not worry; the input data type can be evaluated by eval(input()) <\/em><\/strong>function. However, beware of the use of the eval() function. Let’s take an example of how to use the eval() function.<\/p>\n\n\n\n eval(input()) function<\/strong><\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter a number: 5 <\/strong><\/p>\n\n\n\n (5, <type \u2018int\u2019>)<\/strong><\/p>\n<\/div><\/div>\n\n\n\n Yes, you can! In short, to provide the floating values to the Python program, you need to write float <\/em><\/strong>instead of int <\/em><\/strong>function. Let us understand how the float function works with an easy example:<\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n Enter a number:1.5<\/strong><\/p>\n\n\n\n (1.5, <type ‘float’>)<\/strong><\/p>\n<\/div><\/div>\n\n\n\n Yes, you can do it easily using the split() <\/em><\/strong>function. Moreover, the user can put a split() function to divide the input value with ‘,’. Let’s understand it with the help of an example.<\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n #take the input from the user<\/strong><\/p>\n\n\n\n Enter multiple names<\/strong> <\/p>\n\n\n\n space-separated:- \u20181 2\u2019<\/strong><\/p>\n\n\n\n Enter multiple names <\/strong><\/p>\n\n\n\n space-separated:- [‘1’, ‘2’]<\/strong><\/p>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n NOTE<\/strong>: Also, you can convert each input to the integer value using the map <\/em><\/strong>and int <\/em><\/strong>value function. How? Check the below section.<\/p>\n\n\n\n Yes, it is possible with the help of str.split() <\/em><\/strong>and map() <\/em><\/strong>function. Call str.split() to represent each number. Then use map(func, lis) to create the map objects. Finally, use list(mapping) to change mapping. This is how you can create a map to the list.<\/p>\n\n\n\n Let’s take an example of it:<\/p>\n\n\n <\/p>\n\n\n\n Output<\/strong><\/p>\n\n\n\n # split the data and convert each string number to int<\/strong><\/p>\n\n\n\n \u20181 2\u2019<\/strong><\/p>\n\n\n\n # print the data<\/strong><\/p>\n\n\n\n Enter multiple numbers:- [1, 2]<\/strong><\/p>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n<\/div><\/div>\n\n\n\n Finally, it has been noticed that each program requires data from the user. And, the user can provide the data from the keyboard. But it is always necessary that the program must understand each input data type on its own. That is why users can use input() <\/em><\/strong>function in Python 2 <\/strong>and eval(raw_input())<\/em><\/strong> function in Python 3<\/strong>.<\/p>\n\n\n\n Above, we have provided enough examples that help you to understand how can I read input as numbers. If you still have any queries with your Python program<\/a>, you can comment on it in the comment section. We will try our best to help you with your Python programs.
