我们可以指定分隔符为逗号,并设置expand=True以返回一个新的DataFrame。 # 使用逗号分割split_locations=df['location'].str.split(',',expand=True)# 将拆分后的列重命名split_locations.columns=['City','Country']# 将结果合并到原始DataFrame中df=pd.concat(
Splitting a DataFrame based on certain conditions can be extremely useful in data analysis. Python provides thegroupby()function from the pandas library to split a DataFrame into smaller groups based on values in a specific column. Consider a scenario where we have a DataFramedfcontaining information...

In the above example, we grouped the DataFrame using the Gender column and extracted the rows where the value for this column is F. Using the columns to split DataFrame in Python We can specify the labels or index of the required columns in a list to extract those columns from the DataFra...
To run some examples of split Pandas DataFrame by column value, let’s create Pandas DataFrame using data from a dictionary. importpandasaspdimportnumpyasnp technologies={'Courses':["Spark","PySpark","Hadoop","Python","Pandas"],'Fee':[22000,25000,23000,24000,26000],'Discount':[1000,2300,...
PandasSeries.str.the split()function is used to split the one-string column value into two columns based on a specified separator or delimiter. This function works the same asPython.string.split()method, but the split() method works on all Dataframe columns, whereas theSeries.str.split()func...
在Python Pandas 中使用str.split()函数将字符串拆分为两个列表/列 该字符串可以保存为系列列表,也可以由单个分隔的字符串、多列 DataFrame 构成。 使用的函数类似于 Python 的默认split()方法,但它们只能应用于单个字符串。 语法: Syntax:Series.str.split(pat=None, n=-1, expand=False)Let's define each ...
