for-loop-to-comprehension

Converts all possible For loops to comprehension versions to speed up code. Still a work in progress. Pure python implementation currently.

Not Implemented but will be

1. variable mutation ex: .append(variable + "world") || .append(int(variable))
2. class methods ex: classy.method(x) for x in classy.attributes
3. list comprehensions nested [[y for y in x if y is None] for x in lista]

Examples

Classic ➰

# For loop
squares = []
for i in range(1, 11):
    squares.append(i ** 2)

Converts to...

[i for i in range(1, 11)]

With conditional equate and modulus ❓➗

numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
evens = []
for num in numbers:
    if num % 2 == 0:
        evens.append(num)

Converts to...

[num for num in numbers if num % 2 == 0]

Tuples from Zip of two lists 🤐

names = ['Alice', 'Bob', 'Charlie']
ages = [30, 25, 35]
people = []
for name, age in zip(names, ages):
    people.append((name, age))

Converts to...

[(name, age) for name, age in zip(names, ages)]

String with character check 🧵

text = "hello world"
unique_chars = []
for char in text:
    if char not in unique_chars:
        unique_chars.append(char)

Converts to...

[char for char in text if char not in unique_chars]

Two lists with Zip, atomic output ✌ 1️⃣

names = ['Alice', 'Bob', 'Charlie']
ages = [30, 25, 35]
people = []
for name, age in zip(names, ages):
    people.append(age)

Converts to...

[name for name, age in zip(names, ages)]
