In Python, a string can often be converted into an integer or a float. However, checking if a string can be interpreted as a valid float requires specific approaches. In this chapter, we will explore multiple methods to verify if a string is a float in Python....
{// Here we are converting string to double// and why we are taking double because// it is a large data type in numbers and// if we take integer then we can't work// with double values because we can't covert// double to int then, in that case,// we will get an exception ...

C# Sharp exercises and solution: Write a C# Sharp program to check if a string 'yt' appears at index 1 in a given string. If it appears return a string without 'yt' otherwise return the original string.
