mapfun

mapfun

• mapfun is a function that applies a mapping function to an infinite number of input elements, with options to skip certain elements and selectively apply the mapping to keys and/or values of objects.
• The mapfun function has been developed in JavaScript and Python, offering the same functionality in different programming languages.

Install

pip install mapfun

Import

from mapfun import mapfun

Arguments

• fun : The mapping function that will be applied to each element in the input elements.
  
• ...X :The elements to be mapped .
  
• { "skip" , "key" , "value" } : Object with three optional properties :
  • "skip" : specifies the elements to skip during the mapping process.
  • "key" : boolean flag indicating whether to apply the mapping function to the keys of objects or not. The default value is false
  • "value" : boolean flag indicating whether to apply the mapping function to the values of objects or not. The default value is true

Examples

print(mapfun(lambda a : a + 1,{},4))
# Expected return : 5
print(mapfun(lambda a : a + 1.0,{},4.2))
# Expected return : 5.2
print(mapfun(lambda a : len(a),{},"Ziko"))
# Expected return : 4
print(mapfun(lambda a : a + 5,{},[1, 2, 3, [4]]))
# Expected return : [6,7,8,[9]]
print(mapfun(lambda a : a + 5,range(0,10)))
print(mapfun(lambda a : a + 5,{},(1, 2, 3, [4])))
print(mapfun(lambda a : a + 5,{},{1,2,3}))
print(mapfun(lambda a : a + 5,frozenset({1,2,3})))
print(mapfun(lambda a : a + 5,{},{"a":1,"b":2,"c":3}))
print(mapfun(lambda x:x+1,{},1,2,3,[1,2]))
print(mapfun(lambda x:x+1,{},1,2,3,[1,2]))
