Question

I used this small piece of code and it showed I have a syntax error :

I am a python newbie , can anyone help me with this part of code. A very simple beginners program :

#display

def display(val):

    print("the number ",val)

#main program
while True:

    val = input("Enter an integer between 0 and 9 or -1 to quit") ;
    if val == '-1':
        break 
    if val <= '0' & val >= '9':
        display(val)

it’s showing an error in val =< ‘0’ part

sorry that was a very bad typo from my part , I will edit the question will the traceback:

Traceback (most recent call last):
  File "C:\Users\****\Desktop\ra2\ra.2.py", line 16, in <module>
    if val <= '0' & val >= '9':
TypeError: unsupported operand type(s) for &: 'str' and 'str'

Answer 1

if val =< '0' && val >= '9'

should be:

if val >= '0' and val <= '9',

or simplier:

if '0' <= val <= '9'
