python string format function

we can use the formatted string with format() function in python.

the declaration is like below

str.format(*args, **kwargs)
let's check how to use the function in the example.

in order to check it, I typed codes like below.

print("my favorite fruit is {}".format("apple"))
 
print("{}'s favorite fruit is {}".format("apple""he"))
 
print("{1}'s favorite fruit is {0}".format("apple""he"))
 
print("{human}'s favorite fruit is {fruit}".format(**{"human""she""fruit""banana"}))
cs


you can learn something from above lines.


  1. we can set the format filed with braces {}.
  2. each argument has position and the position is used as index in braces {}
  3. dictionary can be argument and the key is used in each format filed.

 it's time to check the result of above codes.


is it same to your guess?
