Pandas 纳入了大量库和一些标准的数据模型,提供了高效地操作大型数据集所需的工具。Pandas提供了大量能使我们快速便捷地处理数据的函数和方法。你很快就会发现,它是使Python成为强大而高效的数据分析环境的重要因素之一。本文主要介绍一下Pandas中pandas.DataFrame.tz_convert方法的使用。
importpandasaspd# Import pandas library to Python As a next step, we’ll also have to define a pandas DataFrame that we can use in the examples later on: data=pd.DataFrame({'x1':[True,True,False,True,False],# Create pandas DataFrame'x2':['a','b','c','d','e'],'x3':range(...
默认情况下,convert_dtypes将尝试将 Series(或 DataFrame 中的每个 Series)转换为支持pd.NA的 dtypes。通过使用选项convert_string、convert_integer、convert_boolean和convert_boolean,可以分别关闭对StringDtype、整数扩展类型、BooleanDtype或浮点扩展类型的单独转换。
