Changing column names of a data frame

Question

I have a data frame called "newprice" (as seen below), and I'd like to update the column names in my R application.

> newprice Chang. Chang. Chang. 1 100 36 136 2 120 -33 87 3 150 14 164 Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang. Chang.
In fact, I'm doing exactly that:

names(newprice)[1]

<-paste("premium")\snames(newprice)[2]

<-paste("change")\snames(newprice)[3]

<-paste("newprice")
I didn't use a loop since I wanted each column name to be unique, as you can see.

This is the output I get when I paste my programme into the R console:

> newprice(names)[1]

Error: unknown input in -paste("premium") "[1] names(newprice)

-paste(" -paste(" -paste(" -p "> names(newprice)(newprice)(newprice)(newprice)(newprice)

<-paste(“change”)
Unexpected input resulted in an error "names(newprice)(newprice)(newprice)(newprice)(newprice
-paste(" -paste(" -paste(" -p "> newprice(names)[3]
<-paste(“newpremium”)
Unexpected input resulted in an error "newprice(names)[3]
<-paste(“"
I've also tried replacing the paste() function with the c() function—for example, c("premium")—but to no avail.

Could someone please assist me in figuring this out?

import pandas as pd

#define DataFrame
df = pd.DataFrame({'team':['A', 'A', 'A', 'A', 'B', 'B', 'B', 'B'],
                   'points': [25, 12, 15, 14, 19, 23, 25, 29],
                   'assists': [5, 7, 7, 9, 12, 9, 9, 4],
                   'rebounds': [11, 8, 10, 6, 6, 5, 9, 12]})

#list column names
list(df)

['team', 'points', 'assists', 'rebounds']

#rename specific column names
df.rename(columns = {'team':'team_name', 'points':'points_scored'}, inplace = True)

#view updated list of column names
list(df)

['team_name', 'points_scored', 'assists', 'rebounds']
