pandas selects an example of all rows based on the value of the column

This is as follows:

#  Select rows that are equal to some value   with  == 
df.loc[df['column_name'] == some_value]

#  Selects whether the column is a 1 Type value   with  isin
df.loc[df['column_name'].isin(some_values)]

#  The selection of multiple conditions   with  &
df.loc[(df['column'] == some_value) & df['other_column'].isin(some_values)]

#  Select row records that do not equal some value   with   ! =
df.loc[df['column_name'] != some_value]

# isin return 1 Serial value , If you want to choose a value that does not meet this condition ~
df.loc[~df['column_name'].isin(some_values)]
