Imperative Programming

In this paradigm the language specifies a series of instructions to potentially get to an end state (cough Holting Problem cough). Lots of peoples first programs are imperative.

letters = ["a","B","C","d"]
output = []
 
for letter in letters:
	if letter.lower() == letter:
		output.append(letter)
 
print(output) # ["a", "b"]

Here you provide the machine exact steps to what has to be done to produce the output.

There is a sub category of this called Procedural Programming that uses this with functions.

Advantages

• Efficient,
• Emulates low level languages,

Disadvantages
