A collection of utility functions
Project description
utils-anviks
Useful decorators and functions for everyday Python programming.
Features:
Decorators:
@stopwatch
measures execution time of a function (upon being called) and prints the time taken in seconds to the console.@read_file
reads file content and passes it to the decorated function.@catch
catches exceptions from a function.@memoize
caches function results (only works with one positional hashable argument).@enforce_types
checks types of function arguments and return value (raises TypeError if types don't match).
Functions:
b64encode
encodes a string to a base64 string a specified number of times.b64decode
decodes a base64 string a specified number of times.tm_snapshot_to_string
builds a readable string from the giventracemalloc
snapshot.parse_file_content
reads file content and parses it using the provided arguments. It is an alternative to the@read_file
decorator.
Installation
pip install utils-anviks
Usage
import tracemalloc
from utils_anviks import stopwatch, read_file, catch, memoize, enforce_types, b64encode, b64decode, \
tm_snapshot_to_string, parse_file_content
@stopwatch
def some_function():
pass
@read_file('file.txt')
def some_function(file_content):
pass
@catch
def some_function():
pass
@memoize
def some_function(n):
pass
@enforce_types
def some_function(n: int) -> int:
pass
b64encode('string', 3) # 'WXpOU2VXRlhOVzQ9'
b64decode('WXpOU2VXRlhOVzQ9', 3) # 'string'
tracemalloc.start()
arr = [i for i in range(1000000)] # random memory allocation
snapshot = tracemalloc.take_snapshot()
tracemalloc.stop()
print(tm_snapshot_to_string(snapshot))
parse_file_content('file.txt', _class=int) # [1, 2, 3, 4, 5]
