Return Statement Dilemma

Expand Post »

Okay, so, my main problem here, is that I can't get my parameters from my function name to work with the other variables from the function. Here's the code:

Python Syntax (Toggle Plain Text)
def next_block(x):
    p1 = 2
    p2 = 2.3
    p3 = "c"
    p4 = "String"
    p5 = "3.4444"
 
    return p1, p2, p3, p4, p5, print (x)
 
 next_block("testing")
 p1, p2, p3, p4, p5 = next_block()
 
print (p1)
print (p2)
print (p3)
print (p4)
print (p5)
input()
def next_block(x):
    p1 = 2
    p2 = 2.3
    p3 = "c"
    p4 = "String"
    p5 = "3.4444"

    return p1, p2, p3, p4, p5, print (x)

 next_block("testing")
 p1, p2, p3, p4, p5 = next_block()

print (p1)
print (p2)
print (p3)
print (p4)
print (p5)
input()

I'm stumped on this one and I've done lots of experimenting, help would be appreciated.

Re: Return Statement Dilemma

I'm putting some comments in your code, in dive into python's way

python Syntax (Toggle Plain Text)
def next_block(x):  # [1]
    ...
    return p1, p2, p3, p4, p5, print (x) # [2]
 
 next_block("testing") # [3]
 p1, p2, p3, p4, p5 = next_block() # [4]
 
"""
[1]  This function declares the argument x. It must be called with exactly 1 argument. Correct.
[2]  The function returns a tuple with 6 elements. The last element is the return value of the expression print(x), which is always None. No error.
[3]  Here you call next_block, but you don't do anything with the returned tuple which is lost. It's OK.
[4]  2 errors here: you call next_block without arguments, which contraditcs the function's signature (how it must be called), and you try to assign 5 values from the returned tuple, which won't work because the returned value has length 6.
"""
def next_block(x):  # [1]
    ...
    return p1, p2, p3, p4, p5, print (x) # [2]

 next_block("testing") # [3]
 p1, p2, p3, p4, p5 = next_block() # [4]
