Correlation Co-efficient calculation in Python

How would I calculate the correlation coefficient using Python between the spring training wins column and the regular-season wins column?

Name	Spr.TR	Reg Szn
Team B	0.429	0.586
Team C	0.417	0.646
Team D	0.569	0.6
Team E	0.569	0.457
Team F	0.533	0.563
Team G	0.724	0.617
Team H	0.5	0.64
Team I	0.577	0.649
Team J	0.692	0.466
Team K	0.5	0.477
Team L	0.731	0.699
Team M	0.643	0.588
Team N	0.448	0.531

Answer 1

You can use corr (Pearson correlation by default):

df['Spr.TR'].corr(df['Reg Szn'], method='pearson')

output: 0.10811116955657629

Answer 2

If we assume that your data is in a variable of type pandas.DataFrame named df.

from scipy.stats.stats import pearsonr   

correlation = pearsonr(df["Spr.TR"].tolist(),df["Reg Szn"].tolist())[0]
