The Pandas DataFrame can be split into smaller DataFrames based on either single or multiple-column values. Pandas provide various features and functions
Suppose, we have a dataframe that contains multiple columns of bowlers' names having their values containing runs on their six continue balls, we need to calculate the row-wise sum of all the balls except for the last column.Summing up multiple columns into one column without last column...
groupby(column_name).mean() # 按列名分组并计算均值 df[column_name].apply(function) # 对某一列应用自定义函数 数据可视化 import matplotlib.pyplot as plt # 绘制柱状图 df[column_name].plot(kind="bar") # 绘制散点图 df.plot(x="column_name1", y="column_name2", kind="scatter"...
您可以通过,将两列拆分为空格,然后创建它们的乘积,最后对它们进行计数: dt = df[['fruit1','fruit2']].apply(lambda x: x.str.split(', ')) from itertools import prod...
