How to find if a number is a subset of a given integer in Python

I am writing a program with python to find if a number is present as a set in another number

for example: if the number, a = '123456789010234 and I have to find if '4567' is present in a or not.

If you are receiving both the numbers as strings:

a = '123456789010234'
b = '4567'
print(True if b in a else False)

If you are receiving as ints, convert to string and check with in operator.

If you need to check whether the strings are integer at all, or need to handle negative integers, you need to use try-except.

Here you go:

if '123456789010234'.find('4567') > 0: 
     print ("Found!") 
  else: 
     print("Not Found!") 

#Found!

if '123456789010234'.find('4d567') > 0: 
     print ("Found!") 
else: 
      print("Not Found!") 

#Not Found!

If a is a string you can just do this:

a = '123456789010234'
value = '4567'

if value in a:
    print(f'Value {value} present in {a}')
else:
    print(f'Value {value} not present in {a}')

Try using in, if both are integers:

str(num) in str(a)

>>> a = 123456789010234
>>> num = 4567
>>> str(num) in str(a)
True
