The example text we'll be using is a paragraph from Charles Darwin's "On the Origin of Species", which is part of the public domain, packed into a file called text.txt. The most straightforward way to correct input text is to use the correct() method. TextBlob is built on top of NLTK, so it also comes with the installation. Upon finishing the installation, the console output should include something like: Successfully installed click-7.1.2 joblib-0.17.0 nltk-3.5 regex-2020.11.13 textblob-0.15.3 This should install everything we need for this project. Open up a console and install it using pip: Installationįirst, we'll need to install TextBlob, since it doesn't come preinstalled. In this article we'll take a look at how to implement spelling correction in Python with TextBlob. One of these libraries being TextBlob, which is used for natural language processing that provides an intuitive API to work with. Python offers many modules to use for this purpose, making writing a simple spell checker an easy 20-minute ordeal. Modern spell checkers are capable of handling morphology and using statistics to improve suggestions. As hardware and software advanced, so have spell checkers. Called SPELL, it was capable of performing only simple comparisons of words and detecting one or two letter differences. The first program to implement spell checking was written in 1971 for the DEC PDP-10. From autocorrect on our phones, to red underlining in text editors, spell checking is an essential feature for many different products. Here we specify columns argument with “str.lower” fucntion.Spelling mistakes are common, and most people are used to software indicating if a mistake was made. More compact way to change a data frame’s column names to lower case is to use Pandas rename() function. We use Pandas chaining operation to do both and re-assign the cleaned column names.Ĭonvert Pandas Column Names to lowercase with Pandas rename() # Column names: remove white spaces and convert to lower caseĭf.columns= df.().str.lower() Here we also convert the column names into lower cases using str.lower() as before. We can use str.strip() function Pandas to strip the leading and trailing white spaces. Let us create a toy dataframe with column names having trailing spaces.īy inspecting column names we can see the spaces. In addition to upper cases, sometimes column names can have both leading and trailing empty spaces. Now our dataframe’s names are all in lower case. We first take the column names and convert it to lower case.Īnd then rename the Pandas columns using the lowercase names. We can convert the names into lower case using Pandas’ str.lower() function. How To Convert Pandas Column Names to lowercase? Our data frame’s column names starts with uppercase. We will first name the dataframe’s columns with upper cases. We will create a toy dataframe with three columns. And then we will do additional clean up of columns and see how to remove empty spaces around column names. In this post, we will learn how to change column names of a Pandas dataframe to lower case. Cleaning up the column names of a dataframe often can save a lot of head aches while doing data analysis.
