IF statement within multiple FOR loop

Question

I'm fairly new to python and confused with nesting a if function within a for loop

I only want the for loop to continue based on the return value from the if .

In this case, I'm looking to iterate over all Message`s in an inbox, if their read value is False iterate over the attachments of Messages that are not read..

However, using the below I keep getting all attachments saved regardless of their read value being True or False

for Message in mail_folders.get_messages():
    if Message.is_read == False:
        for att in Message.attachments:
            if '.html' in att.name:
                att.save(sv_path)

have I completly written this wrong? or are my indents incorrect?

Update

Using

for Message in mail_folders.get_messages():
    print(Message.is_read)
    if Message.is_read == False:
        for att in Message.attachments:
            if '.html' in att.name:
                att.save(sv_path)

The print statement returns True & False value

thanks

Not entirely sure why but making two changes it is now working.

for m in mail_folders.get_messages(download_attachments = True):
    print(m.is_read)
    if m.is_read == False:
        for att in m.attachments:
            if '.html' in att.name:
                att.save(sv_path)
