What is the python equivalent for names() function in R

Question

I have a code in R, where in the data frame "inputdata" there are multiple columns, and we are replacing the word "new" with "old" in the entire data frame:

names(inputData)[names(inputData)=="new"] <- "old"

How do I perform the same function in python, im a newbie in python ;-;

Answer 1

First of all welcome to the world of python. Try this https://pandas.pydata.org/docs/reference/api/pandas.DataFrame.replace.html

for e.g.

df = pd.DataFrame({'A': [0, 1, 2, 3, 4],
                   'B': [5, 6, 7, 8, 9],
                   'C': ['a', 'b', 'c', 'd', 'e']})
df.replace(0, 5)

BTW if you are looking for just column names update then do below:

df.columns = df.columns.str.replace('new', 'old')
