Python code ignoring if - else statement for unknown reason

Hi im trying to make a python script which will perform google searches with and without websites that you pick based on keywords. However my script doesn't ignore the search action even when a website variable is empty. Instead it just closes the window. Im really new to Python so I would really appreciate it if someone could nudge me in the right direction on this one.

from googlesearch import search
print("Results including the websites you picked:")

if website1 != "":
        for y in keyword_list:
            for i in search(website1+y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
                print (i)
else:
    print("-None")
if website2 != "":
          for y in keyword_list:
            for i in search(website2+y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
                print (i)
else:
    print("-None")
if website3 != "":
          for y in keyword_list:
            for i in search(website3+y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
                print (i)
else:
    print("-None")
if website4 != "":
          for y in keyword_list:
            for i in search(website4+y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
                print (i)
else:
    print("-None")
if website5 != "":
          for y in keyword_list:
            for i in search(website5+y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
                print (i)
else:
    print("-None")
    input("press ENTER to continue")

print("Results not including the websites you picked:")
for y in keyword_list:
    for i in search(y,  tld='com', lang='en', num=1,  start=0, stop=1, pause=2.0):
        print (i)
input("press ENTER to exit")
