okay in this video Id like to cover how you can do more character stuff substitutions specifically handling commas enclosed between double quotes in a comma separated values file so this can often be the case when you have a company named in a column and its company name comma ink or first name comma last name or last name comma first name within a column and the entire file is comma separated but within a particular column there is another embedded comma and this can wreak havoc on other commands like cut and other commands where youre trying to be able to parse out specific columns so its useful to be able to know how to remove that comma in one column without destroying or disrupting all the commas that are the actual column separators so lets take a look at our input file Ive created a slightly different input file for this example so in this example its currently semicolon delimited but were going to change that in a moment to make a comma delimited but for now lets take

The CSV module in Python allows you to read, write and manipulate any data stored in CSV files. In order to read a CSV file, you will need to use the reader method from Pythons csv module that is included in Pythons standard library.
When working with a CSV file it is often necessary to find data contained within and sometimes replace it. Find Replace is used for just this. You can access it from the Edit Find Replace menu or by pressing Ctrl-F on the keyboard.
Exporting the DataFrame into a CSV file Pandas DataFrame tocsv() function exports the DataFrame to CSV format. If a file argument is provided, the output will be the CSV file. Otherwise, the return value is a CSV format like string. sep: Specify a custom delimiter for the CSV output, the default is a comma.
Read and write CSV datasets 7 times faster than with Pandas Its a huge time waster, especially if your datasets measure gigabytes in size.
The join() method takes all lines of a CSV file in an iterable and joins them into one string. Then, we can use replace() method on the entire string and can perform single/multiple replacements. In the entire string, the given text is searched and replaced with the specified text.
After opening the file with file. read() , you can use replace(old, new) to replace the string characters you desire. Keep in mind, since the strings , and , contain quotes, you must put a \ before the quotes to show they part of the string.
pandas is not 100% thread safe. The known issues relate to the copy() method. If you are doing a lot of copying of DataFrame objects shared among threads, we recommend holding locks inside the threads where the data copying occurs. See this link for more information.
Approach Import module. Open csv file and read its data. Find column to be updated. Update value in the csv file using replace() function.
Step 1: Import the module. To import. Step 2 : Read the csv file. Step 3 : Change the date format. Step 4 : Convert column names to lowercase. Step 5 : Replacing Empty spaces with underscore. Step 6 : Rename the column names. Step 7 : Check for Missing Values. Step 8 : Filling Missing Data.
