给定ISO 8601持续时间字符串,如何将其转换为datetime.timedelta？

这不起作用:

timedelta("PT1H5M26S", "T%H%M%S")

我尝试从不同的列表项创建新句子.当我用unicode打印它时给出错误.我可以正常打印(没有unicode).当我尝试将其发布到网站时,其发出同样的错误.我想,如果我能用unicode修复它,它会在它发布到网站时起作用.

p=['Bu', '?u']
k=['yaz?','makale']
t=['ho?','ilgiç']
connect='%s %s %s'%(p[randint(0,len(p)-1)],k[randint(0,len(k)-1)],t[randint(0,len(t)-1)])
print unicode(connect)

And the output is :
Error: UnicodeDecodeError: 'ascii' codec can't decode byte 0xc5 in position 0: ordinal not in range(128)

我有一个像这样的模型

class Section(models.Model):
    section_title = models.CharField(max_length=200)
    section_tiles = models.ManyToManyField(Tile, blank=True)
    on_menu = models.BooleanField(default=False)
    section_is_active = models.BooleanField(default=True)

    class Meta:
        verbose_name = "Section"
        verbose_name_plural = "Sections"

    def __unicode__(self):
        return self.section_title



class Page(models.Model):
    page_title = models.CharField(max_length=200)
    page_sections = models.ManyToManyField(Section, blank=True)
    on_menu = models.BooleanField(default=False)
    page_is_active = models.BooleanField(default=True)

    class Meta:
        verbose_name = "Page"
        verbose_name_plural = "Pages"

    def __unicode__(self):
        return self.page_title

在管理部分我有如下代码：

class SectionTabularInline(admin.TabularInline):
    model = Page.page_sections.through

    class PageAdmin(admin.ModelAdmin):
        inlines = [SectionTabularInline,]

        list_display =[
        'page_title',
        'on_menu',
        ]

        list_filter =[
        'on_menu',
        ]

        search_fields = [
        'page_title',
        ] …
