Guys please I don't seem to fully understand how def functions work in python

Answer 1

You can make functions by the def statement:
1.def CustomFunction(M, N, O):
2. P = (M * N / O)
3. if P == 2:
4. return(M - N + O)
5. else:
6. return(P)
7.
8.print(CustomFunction(4, 3, 6))
9.
>>>>>>>>>>>>>>>>>>>>
Result: 7

Explanation:
CustomFunction takes 3 arguments from the function call (from 8th line in example), in previous example it took M as 4, N as 3 and O as 6.
Inside function definition it calculated the argument M(4) to be multiplied by N(3) and M's and N's income (12) was divided by O(6) so P inside the function is 2,
if P was 2, it returned M - N + O
to the CustomFunction call in 8th line, then it printed M - N + O, what is 7.

If this didn't help, I suggest you to just repeat the module about function definitons and try it out on the Python 3 playground until you can.

For me it made function definition full clear, when I knew, what was function in Python.

Answer 2

def keyword is used for inform parser that your goi g to define one function or an object function and you must write it at start of definition:

def simpleFunc():
print("I am simpleFunc")

This define a simpleFunc function

Answer 3

return is really useful only inside a function for exit to it and return to code that called it a value (but it can return nothing also)

Answer 4

thanks KrOW

Answer 5

👍👍👍 I edited your code with explanations comments

Answer 6

thanks there's a simple project I'm working on.... to calculate two scores using division and addition... lemme get the code and share

Answer 7

or lemme just tell you where I'm stuck at

Answer 8

I don't full understand the return statement

Answer 9

Return statement is simple to understand after few examples:
Think about the len function, for len("Hello") the len function RETURNS 5.
print(len("hello")) == print(5)

def example("A"):
return(A ** 2)

print(example(10)) == print(100)

result: True

Answer 10

thanks guys

Answer 11

thanks Seb TheS your explanation was very clear to me

Answer 12

wow, that's really cool I just check it out.... seems more complex than what I did

Answer 13

CodeX It seem but its not... Read comments and try to figure out that do every statement

Answer 14

okay thanks ....y'all are the best

Answer 15

getOperands function return a list if 2 float elements when op1 get the first (operand[0]) while op2 the second (operand[1])... if you dont know what is a list then dont take care for now, think only that they store currents operands

Answer 16

a little tho

Answer 17

a little tho

Answer 18

I didn't understand when you used:
result = 0
op1 = operand[0]
op2 = operand[1]
