week 1 python help - string formatting ?

[snippsat]

Now that looked at format() forget it,in my option learn and only use f-string.
f-string are far more readable and concise,less prone to error than other ways of formatting,they are also faster!

>>> first_name = 'Eric'
>>> last_name = 'Idle'
>>> print(f'Welcome {first_name} {last_name} to Python forum')
Welcome Eric Idle to Python forum

>>> name = 'f-string'
>>> print(f"String formatting is called {name.upper():*^20}")
String formatting is called ******F-STRING******
 
# f-strings can take any Python expressions inside the curly braces.
>>> cost = 99.75999
>>> finance = 50000
>>> print(f'Toltal cost {cost + finance:.2f}')
Toltal cost 50099.76
 
>>> for word in 'f-strings are cool'.split():
...     print(f'{word.upper():~^20}')
...
~~~~~F-STRINGS~~~~~~
~~~~~~~~ARE~~~~~~~~~
~~~~~~~~COOL~~~~~~~~
