将数据添加到txt文件（并保存在该文件中）

Question

我是一个完全的编程初学者。我试图添加一些信息到一个txt文件，但它不工作。。。它会打印参数，但不会将其添加到txt文件中。所有的帮助将不胜感激

def addpersons(student_number, name, phone_number):

new_person = student_number + name + phone_number
data = data + new_person

with open("data.txt", 'w') as f:
  f.write (data)

print(200300, "Jim", "031213245123")

Answer 1

试试这个：

def addpersons(student_number, name, phone_number):

    data = ""
    new_person = str(student_number) + name + str(phone_number)
    data = data + new_person
    
    with open("data.txt", 'a') as f:
        f.write(data + '\n')

addpersons(200300, "Jim", "03121324")
addpersons(12345, "Jorj", "098765434")

输出：

或者试试这个：

def addpersons(student_number, name, phone_number):

    data = ""
    new_person = str(student_number) + "\t" + name + "\t" + str(phone_number)
    data = data + new_person
    
    with open("data.txt", 'a') as f:
        f.write(data + '\n')

addpersons(200300, "Jim", "03121324")
addpersons(12345, "Jorj", "098765434")

输出：
