Hello everyone, I am new to python and got class assignment from college. Please help me to figure out the problem. The dataset files are given below:

https://www.esrl.noaa.gov/psd/data/correlation/nina1.data

https://www.esrl.noaa.gov/psd/data/correlation/nina4.data

https://www.esrl.noaa.gov/psd/data/correlation/nina34.data

Problem to solve is:

- Calculate nino1+2, nino3, nino4, and nino3.4 indices for the period of data availability?
- Methodology given -Nino X Index computation
- (a) Compute area averaged total SST from Niño X region;
- (b) Compute monthly climatology (e.g., 1950-1979) for area averaged total SST from Niño X region, and subtract climatology from area averaged total SST time series to obtain anomalies;
- © Smooth the anomalies with a 5-month running mean;
- (d) Normalize the smoothed values by its standard deviation over the climatological period.
