suppose if I write something here
suppose eyes I warn the max from some of
the list some list is there suppose so
if I press enter so it is written give
me 36 so it will max function will
return the maximum number from the given
list and as per that you can define your
if you can also find the mean in the
same way you give the list of numbers it
will give the minimum number to you then
and is one more important thing and
suppose in our previous one of the
previous exam of previous program
suppose we see this program here if
suppose here what happens if user gives
capital X Y Z then also it don't just
says that it is a correct password
because it is not case sensitive it is
case sensitive suppose the case is that
I want whether user enters I expressed
it in small or in capital letters then
also it should function so when you want
to defend to two conditions at that time
you have to use an function so using and
you can say that suppose password is
equal to X Y Z should also work the same
way then and I will be closing the end
so the use of and is if both condition
are true then only it will go to true
statement if one of the condition is
false then it will go to the false
statement that means to go for this
function to go to true step for going to
true statement both conditions two
should be true then only it will go to
the true statement one of the okay both
should not be true basically one of the
okay that will be or you both okay here
we have to use or basically because we
want to check that one of the any one of
them if where any one of them is true
then it should go to the true statement
area so at that time we have to use or
so to combine two statement we use the
error if right now if we use
so if you say if you enter password if I
do small letters then also it is saying
correct password you can enter and
suppose if I do capital expose it then
also it is showing correct password you
can enter so in this way you can combine
two conditions using our function and
the use of our is such that he it will
work it will return true if any one
condition is true then next okay then
and and is basically if both conditions
are true then only it will return true
so in this case suppose someone we want
to allow inside whose age is greater
than Phi and lesser than 20 so here we
have used and because both conditions
should be satisfied then only we want to
allow somewhere to enter so in this
thing if two conditions are to be
checked to be whether if we need that
both conditions should be true then we
are to use and the same way as we used
or for any one conditions so in this way
you can use the if statement so that's
