Steps to check if a value can be converted to float or not:

1. Pass the value to the float() method and wrap it inside a try/except block.
2. If the try block run successfully, it indicates that the value is convertible to float.
3. If the except block is executed, it indicates that the value cannot be converted to float.

value = '3.14'

try:
    result = float(value)
    print("Value is convertible to float") 
except ValueError:
    print('Value is not convertible to float')

If we run the above code, we will get the message "Value is convertible to float" since the passed value "3.14" is in fact a float.

Let's try passing a non-float value to raise a "ValueError" in except block.

value = 'sharooq'

try:
    result = float(value)
    print("Value is convertible to float") 
except ValueError:
    print('Value is not convertible to float')

This code will trigger the except block and print the message "Value is not convertible to float".

With this logic, it is possible to create a function which can be reused. Refer to the following code for the reusable function:

def convertable_to_float(string):
    try:
        result = float(string)
        return True
    except ValueError:
        return False


print(convertable_to_float('3.14'))  
print(convertable_to_float('1000')) 
print(convertable_to_float('sharooq.com'))  
print(convertable_to_float('0.8'))  

if convertable_to_float('1111'):
      print("Value is convertible to float") 
else:
   print('Value is not convertible to float')

Running the above code will result in the following output:

We defined a function called "convertable_to_float" to check whether a value is convertible to float or not. The function will return "true" if it is convertible and returns "false" if it is non-converible.
