How to convert a list of strings to integers in Python

How to convert a list of strings to integers in Python.

Here is a step-by-step tutorial on how to convert a list of strings to integers in Python:

Step 1: Create a list of strings​

  • Start by creating a list containing strings. For example, let's create a list called string_list with some strings: ["10", "20", "30", "40"].

Step 2: Use a for loop to iterate through the list​

  • Use a for loop to iterate through each element in the list. This will allow us to convert each string to an integer. For example: 
     for i in range(len(string_list)):
  • Alternatively, you can use a simpler syntax using the "in" keyword: 
     for string in string_list:

Step 3: Convert each string to an integer​

  • Inside the for loop, use the int() function to convert each string element to an integer. Assign the converted value back to the same position in the list. For example: 
     string_list[i] = int(string_list[i])
  • If you are using the simpler syntax with the "in" keyword, you can directly convert the element to an integer: 
     string = int(string)

Step 4: Print the converted list (optional)​

  • If you want to verify the conversion, you can print the converted list. For example: 
     print(string_list)

Step 5: Complete code example​

  • Here's a complete example that demonstrates the conversion of a list of strings to integers: 
     string_list = ["10", "20", "30", "40"]

     for i in range(len(string_list)):
         string_list[i] = int(string_list[i])

     print(string_list)

Output:

     [10, 20, 30, 40]

This is how you can convert a list of strings to integers in Python. Feel free to modify the code based on your specific requirements.
