For loop, if statement and Zip python-CodePudding

It shows unexpected result. The results are shown just for the first element of the lists.

CodePudding user response：

As you are using return It will only check for the first elements.

A return statement is used to end the execution of the function, Replace this with print() will loop over all the elements.

CodePudding user response：

I think your function quality_check() is returning after the first iteration of your for loop. Try:

a= ["Kiran", "Narut","Sasue"]
b= ["Kiran", "Naruto","Sasuke"]

def quality_check(x,y):
  for i,j in zip(x,y):
    if i != j:
      return "Wrong names"
  return "Good to go"

quality_check(a,b)

CodePudding user response：

You should use yield instead of return

a= ["Kiran", "Narut","Sasue"]
b= ["Kiran", "Naruto","Sasuke"]

def quality_check(x,y):
    for i,j in zip(x,y):
        if i == j:
            yield "good to go"
        else:
            yield "wrong"
for element in quality_check(a, b):
    print(element)

this will return required results every time you yield from function it returns a iterable object
