python3 dict comprehension code example
Example 1: python dictionary comprehension
dict1 = {'a': 1, 'b': 2, 'c': 3, 'd': 4, 'e': 5}
double_dict1 = {k:v*2 for (k,v) in dict1.items()}
Example 2: dictionary comprehension in python
sample_dict = {
'a': 1,
'b': 2,
'c': 3,
'd': 4,
'e': 5
}
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)
square_without_dict = {num:num**2 for num in range(11)}
print(square_without_dict)
Example 3: dict comprehension
{i:i*2 for i in range(10)}
Example 4: dict comprehension python
keys=['var1','var2','var3']
my_dict={key:np.zeros(10) for key in keys}
