Pandas DataFrame row count in Python
David Y.
—The Problem
How can I get the number of rows of a Pandas DataFrame in Python?
The Solution
We can do this in one of two main ways:
- Using Python’s built-in
len()function:Click to Copyrow_count = len(my_dataframe) - Using the
DataFrame.shapeproperty, which contains a tuple of the row and column count:Click to Copyrow_count = my_dataframe.shape[0]
The len() function is usually the faster of the two solutions, but shape may be useful in circumstances where we also need the column count.
