What is the main purpose of have inplace= true in "df.dropna(subset = ["price"], axis = 0, inplace = true)"?

Question

My question is about purpose of have inplace= true in "df.dropna(subset = ["price"], axis = 0, inplace = true)"?

Answer 1

This is one of the 2 alternative code styles:

# 1
df.dropna(subset = ["price"], axis = 0, inplace = true)

# 2
df = df.dropna(subset = ["price"], axis = 0)

Choosing one is the matter of personal style, to me the latter one is more readable.
