迭代和计算 Pandas 数据框

Question

As a very very new beginner with Python & Pandas, I am looking for your support regarding an issue.

I need to iterate over columns and find out the maximum value in the concerning rows of a dataframe and write it in a new variable for each row. The number of columns is not manageable, almost 200 columns, therefore I do not want to write each required column id manually. And most importantly that I need to start from a given column id and continue with two columns id increments till a given last columns id.

Will appreciate sample codes, see attachment too.

Answer 1

Try:

df['x']=df.max(axis=1)

Replace x with the name for your desired output column.
