python - Setting up numeric boundaries? -

i'm having trouble setting simple boundary.

i've set minimum , maximum boundary using code here.

def min3(n,m,o):     if (n<m<o or n<o<m):         return(m)     elif (o<m<n or o<n<m):         return(o)  def max3(n,m,o):     if (n>m>o or n>o>m):         return(n)     elif (m>n>o or m>o>n):         return(m)     elif (o>m>n or o>n>m):         return(o) 

this code not print values onto terminal, if use:

def min3(n,m,o):     if (n<m<o or n<o<m):         return("the minimum value is",n) 

then values returned printed in terminal "the minimum value n", seems i'm moving along nicely program.

but, when enter boundary code, is:

def boundaries(a,x,b):     if (x < a):         return false     elif(x >=a , x<= b):         return true 

then run program usual, python3 complains saying

"unorderable types: int() < tuple()"

and can't figure out how either make "x" tuple, or make "a" integer.

does work how expect?

def boundaries(a,x,b):     return true if <= x <= b else false
