[🐍PyTricks]: Functions are first-class citizens in Python

Question

# Functions are first-class citizens in Python:
# They can be passed as arguments to other functions,
# returned as values from other functions,
and
# assigned to variables and stored in data structures.
>>> def myfunc(a, b):
... return a + b
...
>>> funcs = [myfunc]
>>> funcs[0]
<function myfunc at 0x107012230>
>>> funcs[0](2, 3)

Answer 1

here is an example:

def func1(x,y):
print(x+y)

def func2(x,y):
print(x-y)

def func3(x,y):
print(x*y)

myfuncs=[func1,func2,func3]

a,b=2,3
for func in myfuncs:
func(a,b)

Answer 2

In Javascript too, they are 1st class citizens. You should submit these as lessons from lesson factory instead of randomly posting as a post.

Answer 3

I've seen a lot of things in my life, but I've never seen functions being treated like that. Push it into an array! What are you allowing yourself, sir ?!

Answer 4

It's really helpful, thanks.

Answer 5

assigned to variables and stored in data structures.
>>> def myfunc(a, b):
... return a + b
...
>>> funcs = [myfunc]
>>> funcs[0]
<function myfunc at 0x107012230>
>>> funcs[0](2, 3)

Answer 6

def sums(x,y):
return x+y
def do_w(z,x,y):
return z(z(x,y),z(x,y))
a=12
b=15
print (do_w(sums,a,b))

Answer 7

It usually helps for code reuse (less code)

Answer 8

Тимофей Антонов thank you!! This makes it easy to understand
