Lesson 40 of 55
9 mins readPython Text Data Processing & Parsing
In Plain English
Process tabular records, parse string tokens, split delimited text, and format structured computational data cleanly in Julia.
Deep Dive: How It Works
String Splitting: split(str, ",") splits CSV text by commas; strip removes whitespace.
Parsing Numbers: parse(Int, str) and parse(Float64, str) convert text tokens into machine numbers.
Regex Matching: match(r"pattern", str) performs regular expression extraction.
Core Rules to Remember
split() & parse(): Easily convert raw string logs and CSV text into numerical arrays.
r"..." Regex Literals: Native compiled regular expressions with capture groups.

Micro Exercise
Sum Numbers from String
- Given `csv_line = "10,20,30,40"`.
- Split by `","`, parse each into an integer, and calculate `total_sum`.
- Print `"Sum: $total_sum"`.
