harsh183 / mypy-example.py
Last active July 1, 2021 17:26
A small exploration with mypy and python type annotations.
# Simple script I put together showing mypy in action
# standard type annotations - we can give arguments a type and expect a return type
def add(x: int, y: int) -> int:
return x + y
print(add(1, 2))
# we can let it pick within a list of types
from typing import Union

harsh183 / ruby_times_in_kotlin.kt
Last active April 23, 2021 12:53
Recreating ruby's n.times operator on Kotlin. This is for fun, in all seriousness use the repeat(n) operator
fun main() {
// normal function
repeat(3) { print("Yay $it ") }
// => Yay 0 Yay 1 Yay 2
2.times { print("Looop ") }
// => Looop Looop
10.times { print("$it ") }
// => 0 1 2 3 4 5 6 7 8 9

harsh183 / collection_declare_vs_initializer_functions.kt
Last active April 23, 2021 12:53
Comparing directly declaring lists vs initializer functions (using lambdas). The syntax is pretty decent except for maps but to be fair if you're doing this type of thing you should not be using maps.
fun main() {
// Both are the same
val array1: Array<Int> = arrayOf(0, 1, 4, 9, 16)
val list1: List<Int> = listOf(0, 1, 4, 9, 16)
val map1: Map<Int, Int> = mapOf(0 to 0, 1 to 1, 2 to 4, 3 to 9, 4 to 16)
val array2: Array<Int> = Array(5) { it*it }
val list2: List<Int> = List(5) {it*it}
val map2: Map<Int, Int> = (Array(5) {it}).associate {it to it*it}
}
