### f-string
|
|
|
|
[Formatted string literals](https://docs.python.org/3/reference/lexical_analysis.html?highlight=lexical%20analysis#formatted-string-literals), commonly known as f-strings, are strings prefixed with `'f`' or `'F'`. These strings can contain replacement fields, enclosed in curly braces (`{}`).
|
|
|
|
```py
|
|
name = 'John'
|
|
age = 32
|
|
|
|
print(f'{name} is {age} years old') # 'John is 32 years old'
|
|
```
|
|
|
|
### str.format()
|
|
|
|
The [`str.format()`](https://docs.python.org/3/library/stdtypes.html?highlight=str%20format#str.format) method works very much alike f-strings, the main difference being that replacement fields are supplied as arguments instead of as part of the string.
|
|
|
|
```py
|
|
name = 'John'
|
|
age = 32
|
|
|
|
print('{0} is {1} years old'.format(name, age)) # 'John is 32 years old'
|
|
```
