It can be used when a collection is needed to be operated at both ends and can provide efficiency and simplicity over traditional data structures such as lists. 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. In Python, we have the input() function to allow this. The fifth way to check if the input string is an integer or not in Python is by using the combination of any() and map() function in python. That means we are able to ask the user for input. As we know that Python built-in input() function always returns a str(string) class object. Python Input. As we all know, to take input from the user in Python we use input() function. Similar to taking input of integers, we can use float () to take an input from the user and change it to a float. So in python there are some ways to create an array like data structure. To convert the string input to integer we use the int() function over the received input. Likewise, Python 3.x has function 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. To cast (convert) the string of digits into an integer number, we can use the function int(). The default argument is zero.
