In the next short tutorial, you will find how to select rows and columns with Pandas.

To select specific rows and columns from a DataFrame in Pandas, you can use the loc and iloc methods.

Loc

loc is used for label-based indexing. It allows you to select rows and columns by their labels or index names.

Example:

# Selecting a single row by label
df.loc[3]

# Selecting multiple rows by label
df.loc[[1, 3, 5]]

# Selecting a single column by label
df.loc[:, 'column_name']

# Selecting multiple columns by label
df.loc[:, ['column1', 'column2']]

# Selecting specific rows and columns by label
df.loc[[1, 3, 5], ['column1', 'column2']]

Pandas iLoc

iloc is used for integer-based indexing. It allows you to select rows and columns by their integer positions.

Example:

# Selecting a single row by integer position
df.iloc[3]

# Selecting multiple rows by integer position
df.iloc[[1, 3, 5]]

# Selecting a single column by integer position
df.iloc[:, 0]

# Selecting multiple columns by integer position
df.iloc[:, [0, 2]]

# Selecting specific rows and columns by integer position
df.iloc[[1, 3, 5], [0, 2]]

These are some basic examples of how to select rows and columns using Pandas. Depending on your specific needs, you can apply additional conditions and operations to further filter and manipulate the data.
