# Python練習—分組

※第一週在進行分組並實際換好座位後，我們將座位填上線上表格[Ethercalc](https://ethercalc.org/)中，並擷取後利用Python進行分組練習，規則為一組三人，共會分成14組。

## 1.分組排列程式展示

```python
with open("2a raw.txt") as fh:
    rea = fh.readlines()
    #print (rea)

no_list = lambda list: int((sum([(len(list[i])) for i in range(len(list))]))/3)
#簡寫一個for迴圈命名為no_list,目的為求出迴圈執行次數(14次)

t = list()#命名空清單t
for k in range(len(rea)):
    a = rea[k]
    b = a.split()#分割每一行第k位
    #print(b)
    for i in range(0,len(b),3):
        c = b[i:i+3]#每三字串為一次進行迴圈
        t.append(c)#加入清單t
        
for g in range(no_list(t)):#range = 14
    print("第" + str(g+1) + "組:" + str(t[g]))
```

## 2.輸出的結果

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://cda2018.gitbook.io/group3/cheng-mei-zhou-du/week4-6/untitled.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
