Python Pandas是一个很强大的数据分析库,它能够处理各种数据格式,并且能够将它们转化成结构化的数据。在数据分析中,我们需要经常获取到数据类型和DataFrame列的信息,因此本文将介绍如何使用Python Pandas 获取数据类型和DataFrame列的信息。获取数据类型在Python Pandas中,我们可以通过下面的代码获取数据类型:...
从输出结果中我们可以观察到,在访问或获取从DataFrame中分离出来的单列时,其类型被转换为Pandas系列类型,而不考虑该系列中存在的数据类型。在访问pandas系列的单个元素时,我们得到的数据总是以numpy.datatype()的形式存储,要么是numpy.int64或numpy.float64或numpy.bool_,因此我们观察到,Pandas数据框架自动将数据类型...

Just like it says in the subject. Here's an example: In [216]: pd.version.version Out[216]: '0.16.2' In [217]: df = pd.DataFrame(np.random.randint(10,size=(10000,5)),columns=list('abcde')) In [218]: df.head() Out[218]: a b c d e 0 2 6 1 ...
By default, the datatype of the new dummy variables isnp.uint8. The output of pd.get_dummies As an output, the Pandas get dummies function will return a dataframe that contains the new dummy variables. Examples: How to Create Dummy Variables in Python using Pandas ...
