[city] 

Dear [fname]: 

    As a fellow citizen of [city], you and all your neighbours 
on [street] are invited to a celebration this Saturday at

如何合并产生的文件和打印个性化的字母例如第一个地址应该打印：

迈克尔

黎明

锁HART LN

都柏林

亲爱的迈克尔：

都柏林的同胞，你和你的邻居 上锁定HART LN被邀请到一个庆祝这个星期六 都柏林中央公园。带上啤酒和食物！

结论：我怎样才能创建一个函数来合并这2个.txt文件，使个性化的信吗？

我有什么至今：

first_file = open("letter.txt", "r") 

dest_file = open("q2.txt", 'w') 

for line in first_file: 

    v=line.split() 

    for x in v: 

     if x[0]=="fname": 

      dest_file.write(x+"\n") 


first_file.close() 

dest_file.close() 

Answer 1

一旦你已经发现了如何从你的第二个文件读取的变量，你可以通过多种方式代替它们在你的模板。最简单的方法是使用带变量的.format() method。在模板中，您可以通过在.format()方法中添加{fname}并将它们添加为变量来定义标签。

例

"""{fname} {lname} 
{street} 
{city} 

Dear {fname}, 

    As a fellow citizen of {city}, you and all your neighbours 
on {street} are invited to a celebration this Saturday at 
{city}'s Central Park. Bring beer and food!""".format(fname='John', lname='Doe', street='Main St', city='Anywhere') 

输出：

John Doe 
Main St 
Anywhere 

Dear John, 

    As a fellow citizen of Anywhere, you and all your neighbours 
on Main St are invited to a celebration this Saturday at 
Anywhere's Central Park. Bring beer and food!

尽量this.I认为最丑的way.Please等待好的答案。

with open('AdressFile.txt') as f: #assuming as a large file 
    for i in f: 
     fname = i 
     next(f,None) #skipping \n 
     lname = next(f,None) 
     next(f,None) #skipping \n 
     street = next(f,None) 
     next(f,None) #skipping \n 
     city = next(f,None) 
     next(f,None) #skipping \n 
     next(f,None) #skipping ----- 
     next(f,None) #skipping \n 

     with open('letterFile.txt') as f1: 
      temp = f1.read() # assuming as a small file 
      temp = temp.replace('[fname]',fname.strip()) 
      temp = temp.replace('[lname]',lname.strip()) 
      temp = temp.replace('[city]',city.strip()) 
      temp = temp.replace('[street]',street.strip()) 
     print(temp) 

#output 
Michael dawn 
lock hart ln 
Dublin 

Dear Michael: 

    As a fellow citizen of Dublin, you and all your neighbours 
on lock hart ln are invited to a celebration this Saturday at 
Dublin's Central Park. Bring beer and food!

阅读文件：

letter = '' 
q2 = '' 

with open('letter.txt', 'r') as f: 
    letter = f.read() 
f.close() 

with open('q2.txt', 'r') as f: 
    q2 = f.read() 
f.close() 

然后定义一些功能：

def cleanData(query): 
return [item.strip().split('\n\n') for item in query.split('--')] 

def writeLetter(template, variables, replacements): 
    # replace ith variable with ith replacement variable 
    for i in range(len(variables)): 
     template = template.replace(variables[i], replacements[i]) 
    return template 

然后：

variables = ['[fname]', '[lname]', '[street]', '[city]'] 
letters = [writeLetter(letter, variables, person) for person in cleanData(q2)] 

这里有一个[编辑：更新] IPython中的notebook它。
