[Titanic] "Alone" feature should be true when there are no family members

[sandeeps-]

Family members = number of siblings/spouses + number of parents/childen
Family members == 0 ==> Alone is true
Currently it is set as
df['Alone'] = df.Family==1
My change makes it:
df['Alone'] = df.Family!=1

Shouldn't the code then be:

df['Alone'] > 0

instead of

df['Alone'] = df.Family!=1

For the latter one, if the number of family members is say 2, then your code would return True, which is not what we want
