Create a function that attempts to convert a string to a float and returns the float value. Use exception handling to return None if the conversion fails.
Example 1:
Input: "3.14" Output: 3.14
Example 2:
Input: "not a number" Output: None
Use the built-in float() function to convert the string to a float. Be sure to wrap the operation in a try/except block to handle potential exceptions.
def convert_to_float(value):
try:
return float(value)
except ValueError:
return None
print(convert_to_float("3.14"))
print(convert_to_float("not a number"))
