Question

CustomerList = []
CustomerList.append (c1)
CustomerList.append (c2)
CustomerList.append (c3)
CustomerList.append (c4)
CustomerList.append (c5)

for c in CustomerList:
    print ("%8s %25s %35s %15s %15s" % (c.name, c.birth, c.address, c.hkid, "$"+str(c.balance)+"HKD"))

我上面存储了c1-5值，因此我将结果显示为

Jack    Jan, 10th, 1996  430 Davis Ct., San Francisco     M8875895       $40000HKD
Smith  March 24th, 1997  3-5 Tai Koo Shing, Hong Kong     M3133242         $600HKD
Suzy      May 5th, 1995 32 Clearwater Bay Ave. Hong Kong  M8378644      $100000HKD

我是这样的。

我想使用文件访问权限将此信息存储到文本文件中。

我想要做的是使用

inputFile = open("Customer.txt","w")
inputFile.write (....)

我不知道我应该如何列入......空白。

Answer 1

with open("Customer.txt","w") as f: #closes file automtically after loop ends
   for c in CustomerList:
     f.write("%8s %25s %35s %15s %15s \n" % (c.name, c.birth, c.address, c.hkid, "$"+str(c.balance)+"HKD"))

Answer 2

用write替换print语句，然后写一个换行符，然后关闭文件

inputFile = open("Customer.txt","w")

for c in CustomerList:
  inputFile.write("%8s %25s %35s %15s %15s" % (c.name, c.birth, c.address, c.hkid, "$"+str(c.balance)+"HKD"))
  inputFile.write('\n')

inputFile.close()

将2D数组（对象）存储到文本文件中
