Here's how my file looks like
Name  Gender Birth Death
John  Male   1940  1990
Steve Male  1953  1985
John  Male  1933  1965
Sara  Female 1917 1955
I have tried these methods and getting some errors.
file = pd.read_csv('file')
df.insert(6, "Age", file['Death - Birth'])
age = pd.Series([])
and
for i in range(len(df)):
age[i] = df['Death Year - Birth Year']
I want to add a age column which would calculate the age based on birth and death year.
