分割用逗號

Question

我有一個Python的任務有什麼需要我做下面的一個文件，

*創建一個程序：*

1. 按姓氏來檢索和顯示搜索此數據文件聯繫人
2. 細節搜索這個數據文件的出生日期（DD/MM/YYYY）的日期在特定月份檢索和顯示的生日所有聯繫人

3. 添加一個新的個人詳細資料文件

   file = open ("c:\ABOOK.txt", "r") 
   
   myfile = (file.readline()) 
   
   mywordlist = myfile.split() 
   
   
   mylength= len(mywordlist)# reads how long it is 
   print(mylength) 
   count = 0 # counts 
   afound = 0 # counts 
   s_name = input("Enter a surname to be found:") 
   textfile=(file.readlines()) 
   print(textfile[0]) 
   mwl = textfile[0].split(",") 
   mwl1 = textfile[1].split(",") 
   mwl2 = textfile[2].split(",") 
   mwl3 = textfile[3].split(",") 
   mwl4 = textfile[4].split(",") 
   while(count<len(textfile)): 
       print(textfile[count]) 
       count = count + 1 
   print(mwl,mwl1,mwl2,mwl3,mwl4) 
   print(textfile.split(",")) 
   

該文件被打破「」年代和這裏的記事本的提取物;它的六條線。

Answer 1

這裏是你的程序的前兩個部分基本解決注意，您可以改善這個有很多，如沒有硬編碼的文件名，條帶化的新行字符等（的問題，如果你使用這個確切的代碼，這將意味着你不會得到100％），但我會離開，作爲一個任務，爲您：

import sys 

def find_record_by_surname(input_surname): 
    found = False 
    with open("ABOOK.txt", "r") as f: 
     for line in f: 
      surname = line.split(',')[0] 
      if surname == input_surname.title(): 
       found = True 
    return found 

def return_details_by_surname(input_surname): 
    details = [] 
    with open("ABOOK.txt", "r") as f: 
     for line in f: 
      details = line.split(',') 
      if details[0] == input_surname.title(): 
       break 
    return details 

def find_record_by_month_of_birth(input_month): 
    if len(input_month) != 2: 
     input_month = "0" + input_month 
    found = False 
    with open("ABOOK.txt", "r") as f: 
     for line in f: 
      month = line.split(',')[6].split('/')[1] 
      if input_month == month: 
       found = True 
       break 
    return found 

def return_details_by_month_of_birth(input_month): 
    if len(input_month) != 2: 
     input_month = "0" + input_month 
    details = "" 
    with open("ABOOK.txt", "r") as f: 
     for line in f: 
      if line.split(',')[6].split('/')[1] == input_month: 
       details = details + line 
    return details 

if __name__ == "__main__": 
    print("Menu Choices") 
    print("============") 
    print("1: Search contacts by surname") 
    print("2: Search contacts by month of birth") 
    print("3: Add a new contact to ABOOK.txt") 
    print("4: Exit") 
    choice = input("Enter your choice: ") 
    while choice != "4": 
     if choice == "1": 
      input_surname = input("Enter a surname you would like the records for from ABOOK.txt? ") 
      if find_record_by_surname(input_surname): 
       print("The record with the entered surname was found in ABOOK.txt") 
       print("The details for that contact are:") 
       print(return_details_by_surname(input_surname)) 
      else: 
       print("The record with the entered surname was not found in ABOOK.txt") 
     if choice == "2": 
      input_month = input("Enter the month of birth (1-12) you would like the records for from ABOOK.txt? ") 
      if find_record_by_month_of_birth(input_month): 
       print("The details for the contact(s) with the entered month of birth are: ") 
       print(return_details_by_month_of_birth(input_month)) 
      else: 
       print("No record with the entered month of birth was found in ABOOK.txt") 
     if choice == "3": 
      # TO-DO code for adding a new contact 
      print() 
     print("Menu Choices") 
     print("============") 
     print("1: Search contacts by surname") 
     print("2: Search contacts by month of birth") 
     print("3: Add a new contact to ABOOK.txt") 
     print("4: Exit") 
     choice = input("Enter your choice: ") 
    print("Goodbye!")  
    sys.exit(0) 

ABOOK。使用txt文件：

Answer 2

爲了將一個字符串分解只使用

detail_arr = string.split(',') 

detail_arr現在將與您的不同行的數組。

以下是在代碼的示例：

>> str = "Jackson,Samantha,2 Heather Row,Basingstoke,RG21 3SD,01256135434,23/04/1973,sam.jackson@hotmail.com" 
>> str.split(',') 
['Jackson', 'Samantha', '2 Heather Row', 'Basingstoke', 'RG21 3SD', '01256135434', '23/04/1973', 'sam.jackson@hotmail.com'] 

每>>在控制檯中執行的線。

爲了增加細節將它們添加到您的編曲，然後做：

str = ''.join(map(lambda x: x + ',', details_arr))[:-1] 

海峽現在將所有的數組用逗號分隔的，你可以把它寫入文件。

在你的代碼，你不希望在第3行，而是由逗號爲完成拆分的空間數據。

而且你有一段時間沒有退出條款所以你會停留在一個無限循環。

您的代碼應該如下所示：

file = open ("c:\ABOOK.txt", "r") 

data = file.read() 

data_rows = data.split(',') //every 8th row it will start a new entry (7,15,23...) 

現在，姓搜索將在行0,7,15搜索... 的生日搜索將是行6,14,22。 你可以把所有的行都列出來。您可以創建一個計數器，看看在看什麼接觸您選擇：

c = 0 //counter of entry 
for i in xrange(len(data_rows)/8): 
    if data_rows[i+row_number] == val: // row_number depends on what youre trying to match 
     print ''.join(data_rows[c:c+8]) 
    c += 1 

現在你可以告訴項的值相匹配。
