Тоді ви спробуєте давнього друга програміста - автозаповнення редактора коду.

Ви надрукуєте перший параметр функції, `first_name`, тоді крапку (`.`), а тоді натиснете `Ctrl+Space`, щоб запустити автозаповнення.

Але, на жаль, ви не отримаєте нічого корисного:

### Додайте типи

Давайте змінимо один рядок з попередньої версії.

  grep -v "twine" $REQUIREMENTS > requirements_without_twine.txt
  REQUIREMENTS=requirements_without_twine.txt
fi

# Disable the cache dir to save image space, and install packages

// This input was created by taking the instruction productions in
// the old assembler's (6a's) grammar and hand-writing complete
// instructions for each rule, to guarantee we cover the same space.

#include "../../../../../runtime/textflag.h"

TEXT	foo(SB), DUPOK|NOSPLIT, $0

// LTYPE1 nonrem	{ outcode($1, &$2); }
	NEGQ	R11
	NEGQ	4(R11)
	NEGQ	foo+4(SB)

// LTYPE2 rimnon	{ outcode($1, &$2); }

이때 "첫 글자를 대문자로 바꾸는 함수"를 호출해야 합니다.

`upper`였나? 아니면 `uppercase`? `first_uppercase`? `capitalize`?

그때 개발자들의 오랜 친구, 에디터 자동완성을 시도해봅니다.

당신은 `first_name`를 입력한 뒤 점(`.`)을 입력하고 자동완성을 켜기 위해서 `Ctrl+Space`를 눌렀습니다.

하지만 슬프게도 아무런 도움이 되지 않습니다:

### 타입 추가하기

이전 버전에서 한 줄만 수정해봅시다.

저희는 이 함수의 매개변수 부분:

```Python
    first_name, last_name
```
