def add():
    import add_coffee_record
    import imp
    imp.reload(add_coffee_record)

def show():
    import show_coffee_records
    import imp
    imp.reload(show_coffee_records)

def search():
    import search_coffee_records
    import imp
    imp.reload(search_coffee_records)

def modify():
    import modify_coffee_records
    import imp
    imp.reload(modify_coffee_records)

def delete():
    import delete_coffee_record
    import imp
    imp.reload(delete_coffee_record)

def main():
    num=input('\nEnter the number on the menu: ')
    while num != '6':
        if num == '1':
            print()
            add()
        if num == '2':
            print()
            show()
        if num == '3':
            print()
            search()
        if num == '4':
            print()
            modify()
        if num == '5':
            print()
            delete()
        num=input('\nEnter the number on the menu: ')

main()

我的输出如下：

Enter the number on the menu: 2

Description: Thanksgiving Blend
Quantity: 300.0
Description: Christmas Blend
Quantity: 100.0
Description: Thanksgiving Blend
Quantity: 300.0
Description: Christmas Blend
Quantity: 100.0

Enter the number on the menu: 2

Description: Thanksgiving Blend
Quantity: 300.0
Description: Christmas Blend
Quantity: 100.0

Enter the number on the menu: 2

Description: Thanksgiving Blend
Quantity: 300.0
Description: Christmas Blend
Quantity: 100.0

如果第一个输出不会复制，我会喜欢它。有没有办法构建程序，在第一个实例上只使用“import”，在连续的实例上使用“reload”？注意：我无法复制粘贴程序文件而不是导入。我需要使用导入。谢谢。

您可以在导入之前从imp.load_module删除该模块：

def add():
    imp.load_module("add_coffee_record", *imp.find_module("add_coffee_record"))

另一种选择是直接致电<FlipView x:Name="flip" Grid.Row="1" Grid.ColumnSpan="4" Grid.Column="0" Margin="0,0,0,0.333" Grid.RowSpan="2"> <FlipViewItem> <Button Foreground="White" Background="Black" x:Name="btnAdd" Content="Add" Grid.Row="1" Grid.Column="0" HorizontalAlignment="Left" VerticalAlignment="Center" Tapped="btnAdd_Tapped" ></Button> </FlipViewItem> <FlipViewItem> <Button x:Name="btny2" Content="mov" Grid.Row="1" Grid.Column="1" HorizontalAlignment="Center" Tapped="btny2_Tapped" ></Button> </FlipViewItem> <FlipViewItem> <Button x:Name="btnUpdate" Content="Upd" Grid.Row="1" Grid.Column="2" HorizontalAlignment="Right" Tapped="btnupdate_Tapped" ></Button> </FlipViewItem> <FlipViewItem> <Button x:Name="btnRemove" Content="Rem" Grid.Row="1" Grid.Column="3" HorizontalAlignment="Center" Tapped="btnRemove_Tapped" ></Button> </FlipViewItem> </FlipView> private void btnAdd_Tapped(object sender, TappedRoutedEventArgs e) { flip.SelectedIndex++; } private void btnupdate_Tapped(object sender, TappedRoutedEventArgs e) { flip.SelectedIndex++; } private void btny2_Tapped(object sender, TappedRoutedEventArgs e) { flip.SelectedIndex++; } private void btnRemove_Tapped(object sender, TappedRoutedEventArgs e) { flip.SelectedIndex++; }：

function addQuestionField() {
    var get = $("#ques").val();
      for (var i = 1; i < get; i++) {

Answer 2

您需要进入要导入的程序，并将函数名称从main更改为add之类的其他名称。然后注释掉调用该函数，以便您可以在菜单程序中对其进行调用，然后导入该函数的名称。

from add_coffee_record import add
from delete_coffee_record import delete
from modify_coffee_records import mod
from search_coffee_records import search
from show_coffee_records import show


def main():
    choice = -1
    print("Welcome!")
    while choice != 9:
        print ('Select 1 to add records,')
        print('Select 2 to show coffee records')
        print('Select 3 to search coffee records,')
        print('Select 4 to modify coffee records')
        print('Select 5 to delete coffee records.')
        print ('    or 9 to quit.')
        choice = int(input('Enter your choice: '))
        if choice == 1:
            add()
        elif choice==2:
            show()

        elif choice==3:
            search()
    elif choice==4:
        mod()
    elif choice==5:
        delete()
    elif choice==9:
        print('Thank you.')

main()

如何导入然后重新加载没有初始重复
