Join(separator=u' ') 对接收到的元素以指定separator进行合并,相当于 u' '.join(list) >>> from scrapy.loader.processors import Join >>> proc = Join() >>> proc(['one', 'two', 'three']) u'one two three' >>> proc = Join('') >>> proc(['one', 'two', 'three']) u'onetwot...

class scrapy.loader.processors.Join(separator=u’ ‘) 返回用分隔符连接后的值。分隔符默认为空格。不接受Loader contexts。 当使用默认分隔符的时候,这个处理器等同于这个函数: u' '.join 使用示例: >>>from scrapy.loader.processorsimport Join >>> proc = Join() ...
Primitives such as floats, integers and strings are immutable in Python. If you need to update a value in an array of floating-point numbers, use square brackets. main.py my_arr=np.array([1.1,2.2,3.3],dtype=np.float64)my_arr[0]=9.9print(my_arr)# 👉️ [9.9 2.2 3.3] ...
