Groovy is a JVM-based Agile development language that combines many powerful features of Python, Ruby, and Smalltalk. Groovy code can be well combined with Java code, it can also be used to expand existing code. Because of its running characteristics on JVM, Groovy Can use libraries written in other Java languages.

General

Python	Groovy
Repr (x)	X. inspect (), x. dump ()
X. y if x else None	X ?. Y
"% (Foo) s" % locals ()	"$ {Foo }"

Lists List

Python	Groovy
Not x	! X X. empty
Len (x)	X. size ()
For item, idx in enumerate (x ):...	X. eachWithIndex {item, idx-> ...}

Maps

Python	Groovy
{}	[:] // An empty map
Depends: D if used like: for k in d: List (d) if list needed D [iter]. keys () explicitly	D. keySet ()
D. [iter] values ()	D. values ()
[K + 1 for k in d]	D. collect {k, v-> k + 1}
D = dict (zip (k, v ))	K = 1 .. 3 V = 'A'... 'C' D = [:]; k. eachWithIndex {it, I-> d [it] = v [I]} Println d // [1: "a", 2: "B", 3: "c"]

Ranges/Slices range/segment

Python	Groovy
Range (3)	0 .. <3
Range (1, 3 + 1)	1. 3
Range (0, 10, 2)	Not represented as a data type but you can use 0. step (10, 2 ){...}
"Abcdef" [3:]	"Abcdef" [3...-1]

Object access

Python	Groovy
M = 'strip'; getattr ('! ', M )()	M = 'trim ';'! '. "$ M "()
Args = ('A', 2); 'abc'. find (* args)	Args = ['A', 2]; 'abc'. indexOf (* args)
