Let’s now review a simple use case, where we’ll have a list with strings. Join function takes an iterable and joins them into a string. You can use the join function directly to join them into a string. Let us say you have the following list of strings. Use Case: Why Convert Strings to Integers? We will look at four different ways to convert list to string in Python. You’ll get the same results as the first approach: In this case, the separator is the comma string, and the iterable is the fruits list. Then place the list items inside the brackets separated by commas. The strings will be converted to integers: Īs before, you may apply the syntax below in order to verify that the strings were converted to integers: my_list = Say you have a list of strings as follows: fruits 'apples', 'bananas', 'strawberries' And you would like to convert the list into a single string with all the items in the list separated by a comma. To create a list of strings, first use square brackets and to create a list. Using List Comprehension to Convert Strings to Integers in a Python ListĪlternatively, you may use the second approach to convert your strings to integers: my_list = įor our example: my_list = The portion in yellow represents the strings prior to the conversion, while the portion in green represents the integers following the conversion: ![]() Optionally, you may perform a further check to verify that the strings were converted to integers: my_list = Once you run the code, you’ll see the list of integers (without any quotes around the values): Lets take the following example, where there is the. The general syntax looks something like this: int ('str'). The function takes in as a parameter the initial string you want to convert, and returns the integer equivalent of the value you passed. You can then use map in order to convert the strings to integers: my_list = To convert, or cast, a string to an integer in Python, you use the int () built-in function. Here is how the list with the strings would look like: Suppose that you have a list that contains 5 values, where each value is stored as a string (by placing each value within quotes): my_list = ![]() Let’s look at a simple example where we want to convert a string to list of words i.e. The len() function takes the list as its input argument and returns the length of the list. First, we will find the length of the list of strings using the len() function. To convert a list of strings to ints inplace using the int() function, we will use the following steps. Python String split() function syntax is: str.split(sepNone, maxsplit-1) Python Convert String to List. Convert a List of Strings to Ints Inplace Using the int() Function. Using Map to Convert Strings to Integers in a Python List We can convert a string to list in Python using split() function. ![]() You may apply either of the two approaches below in order to convert strings to integers in a Python list:
