Dictionary Comprehension
Hello guys, here we will talk about dictionary comprehension.
Dictionary comprehension is a precise way to create a
new dictionary from the existing dictionary in python
Syntax is,
{key: expression for x in iterable if conditional}
Output
Another example,
Single If statement
Output
We see that the conditional statement worked properly.
Similarly we can use multiple If loop and if-else also.
Nested
dictionary with two dictionary comprehensions
Output
This code without dictionary comprehension will look like this,
We must be careful while using dictionary comprehension as:
1)
They can
sometimes make the code run slower and consume more memory.
2)
They can also decrease the readability of the
code.
