COULD NOT CONVERT STRING TO INT PYTHON SERIES

For example, 1900 is not a leap year, although it can be divided by 4. Note: Leap year has two other conditions: You see, the entered string is converted upfront to an integer and then used for calculation. Print ('You may only enter digits in '2000' format!') After entering the value, the program tells if the entered year is a leap year or not.įor that, the entered value is first converted to int and then leap year formula is used to establish if it is a leap year or not. In the following example, a user is asked to enter a year. The input entered by the user in Python program is taken as a string. To learn more about this, go to int() function tutorial.Īn example of string to integer for leap years Similarly, you may convert to binary and octal as well. The example of using the base argument for string to intĪs such, you may also use the Python int function as follows: The same can be applied to converting a string to float. In the output, you can see a flat integer value.

” and then use the int, as shown in the example below: One other solution is to replace the comma with nothing i.e. However, this may cause problems with different locations. The solution to this can be importing locale:Īnd using the local setting like for the USA: If you try to convert this by using int or float, it will generate an error. Well, what about string numbers with commas like “5,000,000”.

The code for converting list items to float:Īn example of converting a string to int with commas

Similarly, you may use the float instead of int for converting a list containing decimal number strings. The output is a new list with strings converted into integers.Ĭonverting decimal list into float for list items The code: #A demo of string to int in a list If you intend to convert string numbers contained in a python list, then one of the ways to convert those strings into the int is using the list comprehension.Ī new list will be created where you may use int in each iteration as shown in the example below: Note: if you try using the int here, it will generate an error.Ĭonverting string numbers in a Python list to integers The code of using float for converting a string: See the following example for demonstration: You may use the float class for converting a decimal string to a float number. The output is the value of c, which is the sum of the variables str_a and b.Ĭonverting a decimal string into float number Using the same code as in the above example, except converting the string value into an integer by using int. Using int() function for converting a string into an integer The indexing of character in a string starts from ‘0’, and therefore, the string's first character always has the index equal to zero.You may use the Python int and float functions for converting a string to an integer and float numbers before doing any operation, as shown in the examples below. Square brackets are used to access the string elements along with the index position of the string character. In python, the string is a sequence of Unicode characters which include every character and symbol in all languages. Therefore, the characters you input in the system are converted into a binary format using the encoding techniques like Unicode and ASCII. Also, triple quotes are used to display the multi-line quotes.Īs you know, that computer does not deal with characters but instead, it works only with binary numbers. You can use single quotes or double quotes to display the string.

What are strings in python?Ī string is a series of characters inside the quotes. Before understanding the methods to convert the string to float explicitly, let us first go through the strings and float data types in python. Hence, you have to explicitly convert the string into a floating-point value so that you can perform the necessary operations on it. Even though you ask for the floating-point value, the input method in python will fetch the user input as a string object. When you take a user input in python programming while working with terminal or file operations like reading or writing a file, the input is a string object.
