Answer 1

Your logic is correct. But there are some problems with your code.
1. Input returns a string. So when you compare direct input with and int it always gives False ('3' != 3). So you need.to convert input to an integer using int() method

2. Other is the.way that you have positioned else statement.

Below is the corrected version.
d={"a":2,"b":3,"c":4}
n=int(input("enter value"))
for i in d:
if d[i]==n:
print(n,"present at",i)
else:
print("no such value")
