Where in this program content reading from console and print with the sentence. You have to check directly after idn=input() what you get back so what is idn. As we can see in above program the input() method returns a string that’s why the result stored in sum is 4050 (concatenation of two strings) instead of 90. If this is so, then use raw_input() (which returns everything as a string, much like Python 3.x’s input() function does): verifier = raw_input('Verifier code: ') This will stop the issue where the verification code is turned into an integer. In this tutorial, you will learn about the input function with examples. Every floating-point number … Python has two functions for taking in the input from the user or reads the data that is entered through the console and the result of this can be a string, list, tuple or int, etc which is stored into a variable. All Examples of Python input function are in Python 3, so it may change its different from python 2 or upgraded versions. The upper example is no restrictions on input type data. The method is a bit different in Python 3.6 than Python 2.7. Taking Integer Input in Python. Whole numbers (numbers with no decimal place) are called integers. All the values in Python are called "objects". Your "if idn=str:" is complete nonsense, you really should work through a Python tutorial. e.g. Take input from the user. User Input. Python Version Note: Should you find yourself working with Python 2.x code, you might bump into a slight difference in the input functions between Python versions 2 and 3. raw_input() in Python 2 reads input from the keyboard and returns it.raw_input() in Python 2 behaves just like input() in Python 3, as described above. int () takes in two parameters: the string to convert into an integer and the base you want your data to be represented in.
