檔案的簡易操作

 1.寫中文資料到檔案

1 2 3 4

fp=open("test.txt", "w", encoding = "UTF-8") fp.write("好吃芋頭在雲林縣林內鄉烏塗村\n") fp.write("好吃花生在雲林縣元長鄉和虎尾鎮") fp.close()

2.讀取資料

1 2 3 4 5

fp=open("test.txt", "r", encoding = "UTF-8") lines=fp.readlines() for line in lines: print(line) fp.close()

執行結果：

好吃芋頭在雲林縣林內鄉烏塗村

好吃花生在雲林縣元長鄉和虎尾鎮

3.檔案已有換行字元'\n'，輸出可以不用換行

1 2 3 4 5

fp=open("test.txt", "r", encoding = "UTF-8") lines=fp.readlines() for line in lines: print(line, end="") fp.close()

執行結果：

好吃芋頭在雲林縣林內鄉烏塗村

好吃花生在雲林縣元長鄉和虎尾鎮

4.使用with/as來讀取檔案內容

1 2 3 4 5

with open("test.txt", "r", encoding = "UTF-8") as fp: lines=fp.readlines() for line in lines: print(line, end="") fp.close()

執行結果：

好吃芋頭在雲林縣林內鄉烏塗村

好吃花生在雲林縣元長鄉和虎尾鎮

5.字數統計(參考：計算自己程式的行數、字數、字元數)

1 2 3 4 5 6 7 8

with open("test.txt", "r", encoding = "UTF-8") as fp: lines = fp.read().split("\n") line_cnt = len(lines) word_cnt = char_cnt = 0 for line in lines: words = line.split() word_cnt, char_cnt = word_cnt + len(words), char_cnt + len(line) print("File {0} has {1} lines, {2} words, {3} characters".format("test.txt", line_cnt, word_cnt, char_cnt))

執行結果：

File test.txt has 2 lines, 2 words, 29 characters

眼尖的朋友是否覺得有問題呢?

中文字數不能用split()來計算，29字元數就是中文字數。
