![]() You’ll learn how to systematically unpack and understand any line of Python code, and write eloquent, powerfully compressed Python like an expert. Python One-Linerswill teach you how to read and write “one-liners”: concise statements of useful functionality packed into a single line of code. Python programmers will improve their computer science skills with these useful one-liners. ![]() If you’re interested in learning one-liners as well, feel free to check out my book: Python One-Liners Book: Master the Single Line First! □ Learn More: I have compiled an “ultimate guide” on the Finxter blog that shows you the best method, respectively, to convert a CSV file to JSON, Excel, dictionary, Parquet, list, list of lists, list of tuples, text file, DataFrame, XML, NumPy array, and list of dictionaries. The first row of the CSV is used as a header to determine the keys of the dictionary that are mapped to the values defined in the individual rows of the CSV file: More Python CSV Conversions The result of the previous code snippet is a list of dictionaries. Here’s the code to convert that CSV file to a list of dictionaries, one dictionary per row by using the csv.DictReader(file) function: import csvĪ dictionary is a data structure that maps keys to values. If you visualize this CSV in table form, it looks like this: Name Here’s the content of an example CSV file "my_file.csv" used in our code snippet below: Name,Job,Age,Income Let’s have a look at a simple example to demonstrate this solution next! Basic Solution: CSV to List of Dicts – Example
