return vs print in conditional statements within a loop
I am trying to understand why the second function with the return inside the conditionals, will only loop once.
l = [1,2,3,45,6,7]
First working example with print:
def xyz(l):
for i in l:
if i==7:
print('7 found')
else:
print('7 not found')
xyz(l)
Output:
7 not found
7 not found
7 not found
7 not found
7 not found
7 found
Now the function with return statement:
def xyz(l):
for i in l:
if i==7:
return '7 found'
else:
return '7 not found'
Result:
'7 not found'
The loop runs only once for the first element and returns the else value.
Please don`t downvote this, this is a thing I need to understand before continuing to learn python.
Does the return statement exit the loop?
Thanks in advance

Because this is whatreturnis doing. It returns from the function, which will stop any loop. What did you expect it to do?

'return' word ends the execution of the function, 'return something' means the value the function is trying to achieve is: something; it can be visualized as the answer of the function.
'print' word only displays a certain string (text) on the console.
