This does not do what you expect   if var is  stringone  or  stringtwo       dosomething     It is the same as   if  var is  stringone   or  stringtwo       dosomething     Which is always true  since  stringtwo  is considered a  true  value   There are two alternatives   if var in   stringone    stringtwo        dosomething     Or you can write separate equality tests   if var     stringone  or var     stringtwo       dosomething     Don t use is  because is compares object identity   You might get away with it sometimes because Python interns a lot of strings  just like you might get away with it in Java because Java interns a lot of strings   But don t use is unless you really want object identity    gt  gt  gt   a     b      ab  True  gt  gt  gt   a     b  is  abc   2  False   but could be True  gt  gt  gt   a     b  is  ab  True    but could be False

if var     stringone  or var     stringtwo       dosomething      is  is used to check if the two references are referred to a same object  It compare the memory address  Apparently   stringone  and  var  are different objects  they just contains the same string  but they are two different instances of the class  str   So they of course has two different memory addresses  and the  is  will return False
