Pandas: Creating DataFrame from Series

Question

My current code is shown below - I\'m importing a MAT file and trying to create a DataFrame from variables within it:

mat = loadmat(file_path)  # load mat-fi         


        

Answer 1

No need to initialize an empty DataFrame (you weren't even doing that, you'd need pd.DataFrame() with the parens).

Instead, to create a DataFrame where each series is a column,

1. make a list of Series, series, and
2. concatenate them horizontally with df = pd.concat(series, axis=1)

Something like:

series = [pd.Series(mat[name][:, 1]) for name in Variables]
df = pd.concat(series, axis=1)
