Fix “unsupported-assignment-operation” error for Pandas

When using pylint to check my code, it reported an error:

E1137: 'df' does not support item assignment (unsupported-assignment-operation)

Shell

E1137: 'df' does not support item assignment (unsupported-assignment-operation)

for the origin code:

df["column1"] = "hello"

Python

df["column1"] = "hello"

It looks like we have no choice but to use operation .loc in pandas to avoid this error.

# Set all rows in "column1" to "hello"
df.loc[:, "column1"] = "hello"

Python

# Set all rows in "column1" to "hello"

df.loc[:, "column1"] = "hello"
