Question

我是编程新手。我现在正在学校学习python，我遇到了一个错误，我弄清楚了。我一直收到语法错误，我不确定教师或我自己是否错字。

def main():
    num_emps=int(input("How many employee records? "))
    empfile=open("employee.txt","w")
    for count in range(1,num_emps+1):
        print("Enter data for employee#",count,sep='')
        name=input("Name: ")
        id_num=input("ID Number: ")
        dept=input("Department: ")
        empfile=write.(name+"\n")
        empfile=write.(id_num+"\n")
        empfile=write.(dept+"\n")
        print()
    empfile.close
    print("Employee records written to disk")

main()

我一直在

收到错误

empfile=write.(name+"\n")

或者它应该是

empfile.write(name+"\n")

感谢您的帮助

Answer 1

使用empfile.write()代替empfile=write.()

Answer 2

更正和优化的版本：

def main():

    # indentation was missing in your question:

    num_emps = int(input("How many employee records? "))
    empfile = open("employee.txt","w")

    for count in range(num_emps):  # range from 0 to num_emps-1
        print("Enter data for employee #{}:".format(count))  # use str.format(...)

        name = input("Name: ")
        id_num = input("ID Number: ")
        dept = input("Department: ")

        empfile.write(name + "\n")
        empfile.write(id_num + "\n")
        empfile.write(dept + "\n")
        # alternative using Python 3's print function: 
        # print(name, file=empfile)  # line-break already included

        print()
    empfile.close()  # to call the function, you need brackets () !
    print("Employee records written to disk")

main()

此外，您的示例中并不需要编写main()函数。您可以将代码直接放入文件中如果你想要一个合适的main()函数，可以使用这个构造来调用它：

if __name__ == "__main__":
    main()
else:
    print("You tried to import this module, but it should have been run directly!")

它用于确定脚本是直接调用还是由其他脚本导入。
