Reason for choosing this topic

土豆曰：「練英打囉。」

WPM

Words per minute

  • 量度打字與速讀的速度
  • 每五個字視為一個單字

例如：

I run

視為一個字

Let's talk

視為兩個字

WPM 計算

Number_of_keystroke/time_in_minute * percentages_of_accurate_word
Number_of_keystroke/time_in_second * 60 * percentages_of_accurate_word/5

計算時間

time.time()

回傳 1970 年至今經過的秒數

import time
print(time.time())

檔案存取

檔案存取順序

開啟檔案

存取檔案

關閉檔案

開啟檔案

f = open(file, mode)

檔案名稱

開啟檔案的模式

mode
'r' 讀取，預設模式
'w' 寫入，會覆蓋檔案內容
'a' 寫入，若已有內容則附加在末端 
f = open(C:\\users\\user\\file.txt)
f = open('file.txt')

存取檔案

寫法
f.read(size) 依照 size 讀取內容
f.readline() 讀取一整列的資料
f.readlines() 讀取多列資料

Hello World!

This is a sample.

指標起始位置

f.read(7)位置

關閉檔案

f.close()

檔案存取順序

f.open(file, mode)

f.read()

f.close()

實作

LAB : Create a typing test

輸入欲練習的題數

紀錄開始時間

呼叫打字函式

讀檔，計算正確字數、題目長度

記錄結束時間

呼叫結算函式

總共花費時間、WPM、準確率

流程說明：

解說

import time
num = input("輸入題數：")
t1 = time.time()
correct, len_word = typingpractice(num)
t2 = time.time()
result()

    correct = 0
    len_word = 0
    f = open('A Lover\'s Complaint.txt', 'r')
    content = f.readlines()
    for i in range(int(num)):
        content[i] = content[i][:-1]
        print("-"*10)

    print("---結算---")
    print("時間(秒):", t2 - t1)
    print("WPM: {:.2f}".format(len_word/(t2 - t1)*60*correct/len_word/5))

                len_word += len(content[i])
                break
    f.close()
    return correct, len_word

    print("時間(秒):", t2 - t1)
    print("WPM: {:.2f}".format(len_word/(t2 - t1)*60*correct/len_word/5))
    print("準確率: {:.2f}%".format(correct/len_word*100))

t2 = time.time()
result()
