错误书面类文件到csv

class Employee: 
    def __init__(self, name, idno, leavetaken, leavereqd, reason): 
     self.name = name 
     self.idno = idno 
     self.leavetaken = leavetaken 
     self.leavereqd = leavereqd 
     self.reason = reason 

    def __str__(self): 
     return "Name: {}\nID No:{}\nLeave Taken: {}\nLeave Requested: {}\nLeave Reason: {}\n".format(self.name, self.idno, self.leavetaken, self.leavereqd, self.reason) 

n = int(raw_input("Please enter the number of employees: ")) 
employees = [] 

for i in range(n): 
    employee = Employee(
     raw_input("Employee name: "), 
     raw_input("Employee ID no: "), 
     raw_input("Employee leave taken: ") , 

    raw_input("Employee leave requested: ") , 
     raw_input("Employee leave reason: ") 
    ) 
    employees.append(employee) 

print("\n") 

for employee in employees: 
    print(employee)

我无法保存输出哟csv文件。如果你能帮助我，这将是一个很大的帮助。错误书面类文件到csv

如果我尝试以下写入csv，我得到关键错误为零。

keys = my_li[0].keys() 
with open('people.csv', 'wb') as output_file: 
    dict_writer = csv.DictWriter(output_file, keys) 
    dict_writer.writeheader() 
    dict_writer.writerows(my_li)

我曾尝试另一种方式来写他们为CSV

keys = employee[0].keys() 
with open('peo.csv', 'wb') as output_file: 
    dict_writer = csv.DictWriter(output_file, keys) 
    dict_writer.writeheader() 
    dict_writer.writerows(employee)

，我得到的错误是

AttributeError: Employee instance has no attribute 'getitem'

Listwriter功能不也是成功的。任何人都可以让我把解决方案写成csv吗？

糟糕。在尝试缩进时，我给出了代码，并且它已经在我的代码中创建了>符号。 – anonymous

最后一行不应该是dict_writer.writerows（employee [0]）？ – Kewl

在keys = employee [0] .keys（）中获取错误，该雇员实例没有属性getitem – anonymous

这应该为你做。

columns = ['name', 'idno', 'leavetaken', 'leavereqd', 'reason'] 
with open('peo.csv', 'wb') as output_file: 
    dict_writer = csv.DictWriter(output_file, columns) 
    dict_writer.writeheader() 
    dict_writer.writerow({'name': employee.name, 'idno': employee.idno, ...})

迭代列表中的所有员工。

python输出显示了2名员工的详细信息，当我给n = 2但csv只显示最后一个。我哪里出错了？ – anonymous

这个实现使用了'writerow'，它编写了一个单行的对象（一个字典）。所以每次打开文件时都会写入该行。你可以使用'writerows（[dictionaries]）'来代替所有员工。 – nir0s

我在编写代码时尝试写字典时出现错误。你能解释一下吗？ – anonymous
