Generate Functions with Different Constants in Python, JS

Source Code (Python):

#Any function

def f(X):

return X**2;

#Constants for generating functions

Ts = [1,2,3];

#Generate functions

Fs = [(lambda X,T=T: f(X)+T) for T in Ts];

#Call generated functions with default constants

print(Fs[0](3));

print(Fs[1](3));

print(Fs[2](3));

#Call generated functions with specific constants

print(Fs[0](3,1));

print(Fs[1](3,2));

print(Fs[2](3,3));

#EOF

Result:
10
11
12
10
11
12

Source Code (JavaScript, Node.js):

//Shortcuts

log = console.log;

//Any function

function f(X){

return X*X;

}

//Constants to generate functions

Ts = [1,2,3];

Fs = [];

//Function generator loop

for (I in Ts) { //Get index list

..T = Ts[I];

..F = (T => { //A function instance

....return function(X){

......return f(X)+T;

....}

..})(T);

..Fs.push(F);

}

//Test generated functions

log(Fs[0](3));

log(Fs[1](3));

log(Fs[2](3));

//EOF

Result:
The same
