Write a Python function `convert_to_floats(data)` that takes a list of lists as input. Each inner list contains elements that are either strings representing numbers or other non-convertible strings. The function should return a new list of lists where all elements that can be converted to floats are converted, while non-convertible elements remain unchanged. #### Example Usage ```python [main.nopy] input_data = [["3", "4.5", "hello"], ["1.2", "world", "7"]] output_data = convert_to_floats(input_data) print(output_data) # Output: [[3.0, 4.5, "hello"], [1.2, "world", 7.0]] ``` #### Requirements - Iterate through each element of the input list of lists. - Attempt to convert each element to a float. - If conversion fails, keep the element as is. - Return the modified list of lists.
def convert_to_floats(data):
"""
Convert all convertible elements in a list of lists to floats.
Args:
data (list of lists): A list containing sublists with string elements.
Returns:
list of lists: A new list of lists with convertible elements converted to floats.
"""
# Initialize the result list

# Iterate through each sublist
for sublist in data:
# Process each element in the sublist
converted_sublist = []
for element in sublist:
# Attempt to convert the element to a float
# Placeholder for conversion logic
pass
# Append the processed sublist to the result
result.append(converted_sublist)
