How to have multiple conditions for one if statement in python

Question

So I am writing some code in python 3 1 5 that requires there be more than one condition for something to happen  Example   def example arg1  arg2  arg3       if arg1    1          if arg2    2              if arg3    3                  print  Example Text     The problem is that when I do this it doesn t print anything if arg2 and arg3 are equal to anything but 0  Help

Assuming you re passing in strings rather than integers  try casting the arguments to integers   def example arg1  arg2  arg3        if int arg1     1 and int arg2     2 and int arg3     3            print  Example Text      Edited to emphasize I m not asking for clarification  I was trying to be diplomatic in my answer

Might be a bit odd or bad practice but this is one way of going about it    arg1  arg2  arg3     1  2  3   if  arg1    1   arg2    2   arg3    3       print  Example      Anything multiplied by 0    0  If any of these conditions fail then it evaluates to false

I am a little late to the party but I thought I d share a way of doing it  if you have identical types of conditions  i e  checking if all  any or at given amount of A 1 A 2 and B 1 B 2  this can be done in the following way   cond list 1   1   2   3   cond list 2   3   2   1   nr conds 1  if len  True for i  j in zip cond list 1  cond list 2  if i    j   gt  nr conds      print  At least     str nr conds      conditions are fullfilled    if len  True for i  j in zip cond list 1  cond list 2  if i    j    len cond list 1       print  All conditions are fullfilled     This means you can just change in the two initial lists  at least for me this makes it easier

I would use   def example arg1  arg2  arg3        if arg1    1 and arg2    2 and arg3    3            print  Example Text     The and operator is identical to the logic gate with the same name  it will return 1 if and only if all of the inputs are 1  You can also use or operator if you want that logic gate   EDIT  Actually  the code provided in your post works fine with me  I don t see any problems with that  I think that this might be a problem with your Python  not the actual language

Darian Moody has a nice solution to this challenge in his blog post   a   1 b   2 c   True  rules    a    1           b    2           c    True   if all rules       print  Success      The all   method returns True when all elements in the given iterable are true  If not  it returns False   You can read a little more about it in the python docs here and more information and examples here    I also answered the similar question with this info here - How to have multiple conditions for one if statement in python
