Use     See comparison operators  For comparing object identities  you can use the keyword is and its negation is not   e g   1    1    - gt  True 1    1    - gt  False    is     - gt  False  distinct objects  a   b       a is b   - gt  True  same object

There s the     not equal  operator that returns True when two values differ  though be careful with the types because  1     1  This will always return True and  1     1 will always return False  since the types differ  Python is dynamically  but strongly typed  and other statically typed languages would complain about comparing different types   There s also the else clause     This will always print either  hi  or  no hi  unless something unforeseen happens  if hi     hi         The variable hi is being compared to the string  hi   strings are immutable in Python  so you could use the  is  operator      print  hi        If indeed it is the string  hi  then print  hi  else                 hi and  hi  are not the same     print  no hi    The is operator is the object identity operator used to check if two objects in fact are the same   a    1  2  b    1  2  print a    b   This will print True since they have the same values print a is b   This will print False since they are different objects

Use    or  lt  gt   Both stands for not equal   The comparison operators  lt  gt  and    are alternate spellings of the same operator     is the preferred spelling   lt  gt  is obsolescent   Reference  Python language reference

You can use  is not  for  not equal  or       Please see the example below   a   2 if a    2     print  true   else     print  false     The above code will print  true  as a   2 assigned before the  if  condition  Now please see the code below for  not equal   a   2 if a is not 3     print  not equal   else     print  equal     The above code will print  not equal  as a   2 as assigned earlier

You can use    operator to check for inequality  Moreover in python 2 there was  lt  gt  operator which used to do the same thing but it has been deprecated in python 3

Seeing as everyone else has already listed most of the other ways to say not equal I will just add   if not  1      1     This will eval true then false        ie  1    1 is true but the opposite not  is false      print  the world is ending    This will only run on a if true elif  1 1      2    second if     print  the world is ending        This will only run if the first if is false and the second if is true else    this will only run if the if both if s are false     print  you are good for another day    in this case it is simple switching the check of positive     true  to negative and vise versa

There are two operators in Python for the  not equal  condition -  a      If values of the two operands are not equal  then the condition becomes true       a    b  is true   b    lt   If values of the two operands are not equal  then the condition becomes true       a  lt   b  is true  This is similar to the    operator

You can use both    or  lt  gt    However  note that    is preferred where  lt  gt  is deprecated
