How to view and sort csv files in Python

We can view and sort csv files in Python using Pandas or DuckDB

How to view and sort csv files using Pandas

First, we need to install pandas

pip install pandas

Then we can load the csv file into a dataframe.

df = pd.read_csv('path/to/file.csv')

We can view the first few rows of the dataframe using the head method.

print(df.head(n=5))

The n parameter controls how many rows are returned. Increase it to show more rows.

We can view the last few rows of the dataframe using the tail method.

print(df.tail(n=5))

We can sort the dataframe using the sort_values method.

df = df.sort_values('column_name', ascending=true)

Just replace 'column_name' with the name of the column you want to sort by. The 'ascending' parameter controls whether the values will be sorted in 'ascending' or 'descending' order.

We can filter the dataframe using comparison operators. The following statement will filter a dataframe to rows where the value of the 'column_name' column is greater than 5.

df = df[df['column_name'] > 5]

How to view and sort csv files using DuckDB

First, we need to install duckdb for Python

pip install duckdb

The following duckdb query will create a view from the input csv file.

duckdb.sql("""SELECT * from path/to/file.csv""")

Sometimes we have large file and it's impractical to read the whole file. We can read the first 5 rows using the following.

duckdb.sql("""SELECT * from path/to/file.csv limit 5""")

We can sort rows using the ORDER BY clause and a SQL comparison operator.

duckdb.sql("""SELECT * from path/to/file.csv order by 'column_name' ASC limit 5""")

Just change 'column_name' for the column you want to sort by. Use ASC to sort ascending or DESC to sort descending.

We can also filter using SQL comparison operators and the WHERE clause.

duckdb.sql("""SELECT * from path/to/file.csv where 'column_name' > 5 ASC limit 5""")

You can change the 'column_name' to change the column you want to filter by. The operator (>) and value (5) control how the filtering is applied to 'column_name'.
