Can someone please help me figure out how does calling another function into a function function work?

def area_circle(radius): return 3.14*(radius**2)

def inside(hight): area_circle(3) if hight > 2: print("awesome") inside(3) area_circle(3)

Having just a hard time getting the idea in my head, can someone please explain it in details. have no clue what I'm doing in this code by the way. Thanks!

This is the correct code:

def area_circle(radius): 
    return 3.14*(radius**2)

def inside(height): 
    print(area_circle(3))
    #returns: 28.26
    if height > 2: print("awesome") 
    return

# Now you can call area_circle function
print(area_circle(3))
#returns: 28.26

print(inside(3))
#returns: awesome

print(inside(area_circle(3)))
#returns: awesome

def area_circle(radius): 
    return 3.14*(radius**2)

# Now you can call area_circle function
print(area_circle(3))

In this example first "area_circle" returns the valus (3.14*3*2) = 28.26...Than print(28.26)
