dictionary comprehension in python
# dictionary comprehension
# these are a little bit tougher ones than list comprehension
sample_dict = {
'a': 1,
'b': 2,
'c': 3,
'd': 4,
'e': 5
}
# making squares of the numbers using dict comprehension
square_dict = {key:value**2 for key, value in sample_dict.items()}
print(square_dict)
square_dict_even = {key:value**2 for key, value in sample_dict.items() if value % 2 == 0}
print(square_dict_even)
# if you don't have a dictionary and you wanna create a dictionary of a number:number**2
square_without_dict = {num:num**2 for num in range(11)}
print(square_without_dict)
