How do I Get the Row Count of a Pandas Data Frame?

Last Updated on June 16, 2021 by admin

In this article, we will learn to get the row count of a pandas data frame? Programming languages are changing the face of our digital world with so much variety on the web.

it’s difficult to understand the programming features of certain applications.

The efforts programmers put in to explain the machine about the work that’s needed to be done is impeccable.

they have made our work easier.

We never seem to understand how this data brings to certain users’ row count of a pandas data frame.

Panda’s data frame

Panda’s data frame is an easy way to store and analyze complex data it can merge reselect and clean data.

It is said to be the easiest data management which analyzes data with the help of the python programming language.

Data frames are a mechanism in which strong procedures are built-in and on the other hand Python system.

Which is related to these objects and procedures work into them so our required data should be in.

These data frames are used accordingly while our Data can appear from many files various sources.

Which are Excel files, CSV files, and database records

Python programming language do consider a high-level language that focuses on code clarity for being readable.

(OOP) object-oriented approach

Its main purpose to make programmers put down analytical codes its (OOP) object-oriented approach makes it more reliable to do coding some followers of python.

Who are expert and skillful individuals have known as Pythonistas The design philosophy of python is based on “Zen of Python” Some versions are Python 2.0, Python 3.0, Python 2.6.x, and 2.7.x.

Pandas data frame is simply a table with rows and columns and the data itself one can do basic actions such as add rename delete and select with rows and columns.

We can select the column with its name and rows by processing its special number location.

The panda’s data frame has many qualities it has vast features, good data presentation, little write-ups, increased relevance of work, and do creation for the python system.

And here you go:


import numpy as np
import pandas as pd
import perfplot

perfplot.save(
"wholeblog.png",
setup=lambda n: pd.DataFrame(np.arange(n * 3).reshape(n, 3)),
n_range=[2**k for k in range(25)],
kernels=[
lambda df: len(df.index),
lambda df: df.shape[0],
lambda df: df[df.columns[0]].count(),
],
labels=["len(df.index)", "df.shape[0]", "df[df.columns[0]].count()"],
xlabel="Number of rows",
)

Row counting methods

There are various row counting methods in pandas data frame Firstly to execute the data frame.

Shape properties to find the number of rows Second is to count rows by executing the command data frame count.

Thirdly, to use data frames .index which contains row labels we can compute the duration of those labels to find.

the rows Fourthly, the len method which can help us count the rows, by using a data frame. axes.

You are to install the following:


import numpy as np
import pandas as pd

wholeblog_df = pd.DataFrame({"Letters": ["a", "b", "c"], "Numbers": [1, 2, 3]})
print(wholeblog_df)
