You can perform arithmetics using the eval() function, and it will return the integer data type. Print(numeval) # printing converted string Print(type(numeval)) # Checking numeval datatype Numeval = eval(num) # Coverting string num to int numeval
Python convert string to int different base code#
However, the eval() function is generally not recommended because it can be dangerous (i.e., it can allow malicious code to execute). num = "1234"įinally, it's also worth mentioning that Python has a built-in eval() function, which evaluates a string as if it were a Python expression. However, just like int(), if the string is not a valid floating-point number, float() will throw a ValueError.Īfter the conversion from string to float, we can then use the int() function to truncate the decimal and convert it to an integer. The float() function takes in a string as an argument and returns the corresponding floating-point value. We can also use the built-in float() function to convert a string to an int. ValueError: invalid literal for int() with base 10: '1234a' Using the float() funtion For instance, int('1234a') will result in a ValueError. If the string is not valid, then int() will throw a ValueError. Finally, we confirm the datatype of number, which is now a string, and print the converted string to the console. We then convert the string num to int using the int() function and assign it to the number variable.
By checking the datatype of num, we can confirm that it is a string. In this example, we initialize the num variable to "1234". Print(number) # printing converted string Print(type(number)) # Checking number datatype Number = int(num) # Coverting string num to int
If we have a string '1234', calling int('1234') will return the integer 1234. The syntax is as follows: Advertisements int(string) The int() function takes in a string as an argument and returns the corresponding integer value. One way to convert strings to integers is by using the built-in int() function. In Python, there are several ways to accomplish this task. You might also be reading in data from a file and want to convert it into a form that's easier to work with. Sometimes, we need to convert a string to an integer for mathematical operations or storage in a database. Converting a string to an integer is a common operation in programming.
