3) In February 2012 (the 2012 data is indicated by 1 in the yr column), there were issues with the temp and atemp readings, resulting in some null values in the dataset for that specific month. To address this, filling the missing data with the overall dataset's average temperatures wouldn't be accurate enough. Instead, the task is to fill these null values with the respective mean temperature values for each column for February 2012 (yr=1, mnth=2) specifically. To match the data currently in the file, you should round the mean value for the temp column to 2 decimal places before using it to fill the null values in that column. Similarly, for the atemp column, the mean value should be rounded to 4 decimal places before being used to fill the null values in that column. Note: In your code, you are required to calculate the mean using Pandas and refrain from hard-coding the mean value
