EXCEPTION HANDLING

Estimated time

15-25 minutes

Level of difficulty

Medium

Scenario

Your task is to write a function able to input integer values and to check if they are within a specified range.

The function should:

  • accept three arguments: a prompt, a low acceptable limit, and a high acceptable limit;
  • if the user enters a string that is not an integer value, the function should emit the message Error: wrong input, and ask the user to input the value again;
  • if the user enters a number which falls outside the specified range, the function should emit the message Error: the value is not within permitted range (min..max) and ask the user to input the value again;
  • if the input value is valid, return it as a result.

Test data

Test your code carefully.

This is how the function should react to the user's input:

Enter a number from -10 to 10: 100 Error: the value is not within permitted range (-10..10) Enter a number from -10 to 10: asd Error: wrong input Enter number from -10 to 10: 1 The number is: 1


CODE:

def read_int(prompt, mini, maxi):
    
    try:
        assert prompt.isdigit(),"Error:wrong input"
        if not(mini<=int(prompt)<=maxi):
            raise ValueError("Error:the value is not within the specified range")
        else:
            print(prompt,"in try")
            return prompt
    except (AssertionError ,ValueError) as A:
        print(A)
        prompt=read_int(input("Enter a number from -10 to 10: "), -10, 10)
        return prompt
        
    

v = read_int(input("Enter a number from -10 to 10: "), -10, 10)

print("The number is:", v)

20. Valid Parentheses Easy 18.3K 1K Companies Given a string  s  containing just the characters  '(' ,  ')' ,  '{' ,  '}' ,  '['  and  ']' , determine if the input string is valid. An input string is valid if: Open brackets must be closed by the same type of brackets. Open brackets must be closed in the correct order. Every close bracket has a corresponding open bracket of the same type.   Example 1: Input: s = "()" Output: true Example 2: Input: s = "()[]{}" Output: true Example 3: Input: s = "(]" Output: false   Constraints: 1 <= s.length <= 10 4 s  consists of parentheses only  '()[]{}' . My code: class Solution: def isValid(self, s: str) -> bool: a='([{' b=')]}' c=[] for i in s: if i in a and s.count(i)!=s.count(b[a.find(i)]):#checks if no.of opening element==no of closing element print(i,b[...
