You should just use pd.read_csv to do the work.

df = pd.read_csv("WEO_Data.csv")

If you are planning to do amendments in the data, you can do so after reading it into Pandas dataframe.

Use read_csv with encoding='utf-16' parameter:

file="https://raw.githubusercontent.com/gambler2020/Data_Analysis/master/Economy/WEO_Data.csv"

df = pd.read_csv(file, encoding='utf-16')

print (df.head())
