In this Article I'm going to be talking about f-strings and some of the cool things that you can do with them. so most of you are probably already aware of what f strings are.

## 🎯 f-strings

Also called “formatted string literals,” f-strings are string literals that have an f at the beginning and curly braces containing expressions that will be replaced with their values.

## 1.Put a '=' Sign afterwards

One of the really cool things that you can do is just put an equals sign afterwards,eg-

### Code -

``````word = 'Hello World'
num = 152
print(f'The value of word is f{word}')
print(f'{word=}')

print(f'The value of num is f{num}')
print(f'{num=}')
print(f'{num + 8 =}')
``````

### Output -

``````The value of word is Hello World
word='Hello World'
The value of num is f152
num=152
num + 8 =160
``````

## 2.Conversions

So if you're not aware,  inside the curly braces of an f string after the expression you can put a ```!a ,!s , !r ``` , and  what these do is instead of printing the value of this thing, it will additionally do some extra thing on top of that.

!r - repr() 'The repr() method returns a string containing a printable representation of an object.'

!a - ascii 'all the non ascii characters get replaced with an ascii safe escaped version of it'

!s - string conversion operator 'formating'

### Code -

``````def conversion():
str_value = "Hello World 😀"
print(f'{str_value!r}')
print(f'{str_value!a}')
print(f'{str_value!s}')

conversion()

``````

### Output -

``````'Hello World 😀'
'Hello World \U0001f600'
Hello World 😀
``````

## 3.Formatting

':' after the variable

### Code -

``````import datetime

def formatting():
num_value = 475.2486
now = datetime.datetime.utcnow()

#Formats the datee in the given format
print(f'{now=:%Y-%m-%d}')

# Rounds the decimal to 2 digits
print(f'{num_value:.2f}')

formatting()
``````

### Output -

``````now=2021-08-04
475.25
``````
