Easy use of F-Strings with Python.

F-Strings

Here, I am going to jump straight to printing out strings with Python. Take a look at this code using place holder format method.

    first_name = 'sam'
    last_name = 'sonter'

    intro = "My name is {} {}".format (first_name,last_name)
    print(intro)

    output:  My name is sam sonter

Python can also allow us to use the F-String to get same output. Check this out.

    first_name = 'sam'
    last_name = 'sonter'

    intro = f"My name is {first_name} {last_name}" 
    print(intro)

    output:  My name is sam sonter

I got rid of the format method and introduced the F string. I now put the variables inside the placeholders making the block of code easier to understand.

Now, I am going to use a dictionary in the next example.

    person = {'name': 'Sam', 'height': 188}
    sentence = "My name is {} I am {} cm tall".format(person['name'],person['age'])

    print(sentence)

The next example is pretty much the same with the first one except here we are using a dictionary. Now, let's use the F string.

    person = {'name': 'Sam', 'height': 188}
    sentence = f"My name is {person['name']} I am {person['height']} cm tall"

    print(sentence)

Many people might make syntax errors by using the wrong quotes. If you pay attention you can see i used double " outside my statement and single ' inside the statement to avoid syntax errors.

That is it for this article, thanks for reading and I hope you find this useful.
