#look like: your_srting % values
#when:
#your_string = "any king of character %format"
#type(value) = tuple
# A falg can be added between the % and the format
#Exemple:
print("there is %d ducks in the lake" % 34) #>>> there is 34 duck in the lake
# Or
your_string = "%d of the %d ducks are ducklings"
values = (12, 32)
print(your_string % values) #>>> 12 of the 34 ducks are ducklings

%X to display as an hexadecimal intedger (with lettre in uppercase)
%o to display as an octal integer
%u to display as an unsigned integer
%c to display in ascii (process "chr(value)")
#Floats
%f to display in default float form
%e to display in scientific writing (with a lowercase e to expess exponent)
%E to display in scientific writing (with an uppercase E to expess exponent)
