How to delete the digits？

Question

A number 4529, I want to delete 2 digits, and let the result become minimum. For example, 4529-->29, 4529-->52, 29 is minimum, which is what I want.

Answer 1

a=int(input())
mins=a%100
while a>9 :
if mins>(a%100) :
mins=a%100
a=a//10
print(mins)

For Input: 12345
Output: 12 because in 12345, 12 is minimum
For input 4528, output is 28
Is this you are looking?

Answer 2

mynum = 4529
strmynum = str(mynum)

mylist = []

for x in range(len(strmynum)-1):
mylist.append(int(strmynum[x:x+2]))
print(min(mylist))
