Question

我尝试了一段代码并且它运行良好，但问题是它有一个我想要的行中的file.write值。但它不起作用。代码是：

start = input('Enter your starting point:')
stop = input('enter your destination:')
count = input('Ticket count:')

p = 10 * int(count) #a + b  
q = 20 * int(count)#a + c
r = 30 * int(count)#a + d
s = 10 * int(count)#b + c
t = 20 * int(count)#b + d
u = 10 * int(count)#c + d

if start == 'a' and stop == 'b':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(p))
    file.close()
    print ('Your cost is usd ',p)
elif start == 'a' and stop == 'c':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(q))
    file.close()
    print ('Your cost is usd ',q )
elif start == 'a' and stop == 'd':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(r))
    file.close()
    print ('Your cost is usd ',r )
elif start == 'b' and stop == 'c':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(s))
    file.close()
    print ('Your cost is usd ',s )
elif start == 'b' and stop == 'd':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(t))
    file.close()
    print ('Your cost is usd ',t )
elif start == 'c' and stop == 'd':
    file = open(r"C:\Users\the\Desktop\py\2.txt " , 'w+')
    file.write('Location: '+ start +' > '+ stop +\
      'Ticket count: '+ count +\
      'Total fare: ' + str(u))
    file.close()
    print ('Your cost is usd ',u )
else:
    print('you entered wrong values')

请给我一个解决方案或修复代码。有一点要提到我在python中的新手，这是我尝试的第一个程序。希望能解决这个问题。

我希望这段代码以单独的行写入，你必须在每行的末尾添加一个“\ n”：

file.write('Location: '+ start +' > '+ stop +\
  'Ticket count: '+ count +\
  'Total fare: ' + str(r)+"\n")

对于Windows，您可能需要“\ r \ n”

我怎么能在这里使用换行符？
