General
All tips on the Python wiki page also apply to Coconut.
Documentation for Coconut is available here 🥥.
Functions
Use implicit function application (f x instead of f(x)) when every parameter is represented by a variable or constant value, with the exception of string literals.
print(100)
print 100
c="Coconuts"
print(42,c)
print 42c
Use infix representation for functions with two parameters.
print(42,"Coconuts")
42`print`"Coconuts"
Use the implicit form of the => operator in anonymised lambdas with one parameter (can be accessed via _).
*map(x=>print(x+21),range 5)
*map(=>print(_+21),range 5)
Integer coefficients
When multiplying an integer literal and a variable, * can be omitted, such as 2x instead of 2*x.
Arguments
There is no need to import sys to get the list of arguments, as it's possible to access it via an already imported module os.
import sys;*map(print,sys.argv)
*map(print,os.sys.argv)
Modules
Coconut provides a few other modules without import, as well as several modules not part of the standard library. These include useful modules like more_itertools or inflect, run help('modules') to print a list of all available modules.
Unicode operators
Some operators have unicode alternatives that could be useful for chars scoring, full list here
