1. Develop a function to generate a set of Pearson Correlation Coefficients for a given data file (This function should make use the function developed in FR4 to generate a Pearson Correlation Coefficient for every pair of columns in the data read into memory in FR3. The function should return a list of tuples, each tuple containing the two column names and associated correlation coefficient value) Do not use Python modules such as math or libraries such as Pandas or NumPy
