# selecting a range of rows:
df.iloc[0:3]
# selecting all rows, with columns within an index range:
# all rows, 1st- 3rd columns, sliced at second index:
df.iloc[:, 0:3]

df.loc[df['column_name'] < 5]
#boolean indexing fro one column:
df.loc[df['column_condition'] < 12, ['column_desired']]
loc vs iloc pandas
>>> s = pd.Series(list("abcdef"), index=[49, 48, 47, 0, 1, 2])
49 a
48 b
47 c
0 d
1 e
2 f
>>> s.loc[0] # value at index label 0
'd'
>>> s.iloc[0] # value at index location 0
'a'
>>> s.loc[0:1] # rows at index labels between 0 and 1 (inclusive)
0 d
1 e
>>> s.iloc[0:1] # rows at index location between 0 and 1 (exclusive)
49 a
