# str (5-str.org)

Short for "string," a plain piece of text like a name, address, or sentence. People say "str" when they mean words or letters as data, not numbers or special codes.

## What a model may hear
- string data type (Python, C, Java, and most programming languages): Treat the value as a sequence of characters, enforce text operations, and reject math or bitwise logic
- structure or struct (C, C++, systems programming): Expect a fixed memory layout, packed fields, or binary record format
- STR file format (bioinformatics, chemistry): Look for Short Tandem Repeat data or molecular structure files
- stream (Unix, networking, I/O APIs): Assume a continuous flow of bytes or data channel, not a stored value
- STR instruction (ARM assembly, low-level hardware): Interpret as a store-to-memory command with register operands

## Where people and models part ways
- Says: "str my data"
  Means: Label my text data as a string
  May be taken as: Model assumes Python type annotation and may reject non-text or apply str() conversion rules
  Say instead: "treat this as plain text"
- Says: "parse the str"
  Means: Read and understand the text
  May be taken as: Model looks for a .str file extension or bioinformatics format parser
  Say instead: "parse this text string"
- Says: "str of numbers"
  Means: Numbers written out as text like "123"
  May be taken as: Model stores as numeric type or applies string encoding that breaks digit sequences
  Say instead: "the digits one-two-three as text"
- Says: "fix the str"
  Means: Correct spelling or grammar in the text
  May be taken as: Model modifies struct memory layout or rewrites ARM store instruction
  Say instead: "correct the text"

## Tips
- Say "text" or "plain text" instead of "str" when you do not need a programming type
- If you mean Python specifically, say "Python string" to avoid struct or stream confusion
- Quote the content to signal you mean text: str("like this")
- Avoid "str" alone when discussing files; say "string value" or "text file"
- In code contexts, write the full word "string" in comments for clarity

## Often confused with
- string: the full word, unambiguously text
- struct: memory layout, not character sequence
- stream: flowing data, not a stored value
- char: single character, not a sequence
- txt: file extension, not a data type
- std::string: C++ specific, not generic
