Select rows from a DataFrame based on column values?

#To select rows whose column value equals a scalar, some_value, use ==:
df.loc[df['A'] == 'foo']

#To select rows whose column value is in an iterable, some_values, use isin:
df.loc[df['B'].isin(['one','three'])]

#Combine multiple conditions with &:
df.loc[(df['column_name'] >= A) & (df['column_name'] <= B)]

pandas return row

1. 	Selecting data by row numbers (.iloc)
	# myrow = data.iloc[<row selection>]
 	myrow = data.iloc[7]
    myrow = data.iloc[0:9]
    
2. 	Selecting data by label or by a conditional statement (.loc)
	# myrow = data.loc[<row selection.]
  	myrow = data.loc['University ABC']
    
3. 	Selecting in a hybrid approach (.ix) (now Deprecated in Pandas 0.20.1)
	# Works like a .loc but also accepts integers - may lead to unexpected results
