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_wordNumber_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 timenum = input("輸入題數：")
t1 = time.time()
correct, len_word = typingpractice(num)
t2 = time.time()
result()def typingpractice(num):
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("Try this:", content[i])
print("長度：", len(content[i])) while True:
ans = input("ans: ")
if len(ans) != len(content[i]):
print("輸入長度為", len(ans), "，字數不符重新輸入")
else:
for j in range(len(content[i])):
if ans[j] == content[i][j]:
correct += 1
len_word += len(content[i])
break
f.close()
return correct, len_worddef result():
print("---結算---")
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))import time
def typingpractice(num):
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("Try this:", content[i])
print("長度：", len(content[i]))
while True:

for j in range(len(content[i])):
if ans[j] == content[i][j]:
correct += 1
len_word += len(content[i])
break
f.close()
return correct, len_word
def result():
print("---結算---")
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))
num = input("輸入題數：")
t1 = time.time()
correct, len_word = typingpractice(num)
t2 = time.time()
result()完整程式碼
