python typing function code example

Example 1: python typing effect

from time import sleep
import sys

string = "The Battle Cats For Life" # Whatever string you want

for letter in string:
  sleep(0.01) # In seconds
  sys.stdout.write(letter)
  sys.stdout.flush()

Example 2: python typing void function

def function(param: str) -> None:
  # A function that doesn't return anything,
  # has None as return type.
  print("hey")

Example 3: python typing list of strings

from typing import List

def my_func(l: List[int]):
    pass

Example 4: typing generator python

# Iterator
def infinite_stream(start: int) -> Iterator[int]:
    while True:
        yield start
        start += 1

# Generator        
def infinite_stream(start: int) -> Generator[int, None, None]:
    while True:
        yield start
        start += 1

Example 5: typing python

from collections.abc import Iterable

def zero_all_vars(vars: Iterable[LoggedVar[int]]) -> None:
    for var in vars:
        var.set(0)

Example 6: python type hint list

# For collections, the name of the type is capitalized, and the
# name of the type inside the collection is in brackets
x: List[int] = [1]
x: Set[int] = {6, 7}
  
# For simple built-in types, just use the name of the type
x: int = 1
x: float = 1.0
x: bool = True
x: str = "test"
x: bytes = b"test"
