Python对基础数据提供了类型转换,比如用int函数将数据转为整数,float将对象转为浮点数,str将对象转为字符串,list将对象转为列表,tuple将对象转为元组,set将对象转为集合。其中列表、元组、集合可以通过对应函数相互转换,但是可能会丢失部分信息,比如排序,以及重复成员只会保留一个。 以上均不改变原来的数据的值,而是...

Return a translation table usable for str.translate(). If there is only one argument, it must be a dictionary mapping Unicode ordinals (integers) or characters to Unicode ordinals, strings or None. Character keys will be then converted to ordinals. ...

A. int B. list C. float D. string 答案：D（注：这里原选项有误，应该是str，而不是string。Python基本数据类型有int、float、bool、str、list、tuple、set、dict等，这里认为是考察基本数据类型概念，string表述不准确）解析：Python基本数据类型有int（整数）、float（浮点数）、bool（布尔值）、str（字符串...
If this is not desired, eitherdelay the creation of the bar to the cell where it must be displayed, or create the bar with display=False, and in a later cell call display(bar.container):from tqdm.notebook import tqdm pbar = tqdm(..., display=False)...
