Why am I getting the invalid syntax?-CodePudding

I am new to Machine learning. I am trying to plot the input data. but it gives me syntax error:

"C:\Users\shafi\AppData\Local\Temp/ipykernel_14876/3654013207.py", line 1 plt.scatter(year,per capita income (US$),color='blue',marker=' ') ^ SyntaxError: invalid syntax

import pandas as pd
import numpy as np
from sklearn import linear_model 
import matplotlib.pyplot as plt


df=pd.read_csv('E:/CV (ALL FOR JOB)/ALL PROJECTS/5. IMAGE DETECTION/canada.csv')
df
df.head(3)

%matplotlib inline 
plt.xlabel('year',fontsize=20)
plt.ylabel('per capita income (US$)',fontsize=20)
plt.scatter(df.year,df.per capita income (US$),color='blue',marker=' ')

CodePudding user response：

per capita income (US$) is not a valid python identifier:

plt.scatter(df.year, df['per capita income (US$)'], color='blue', marker=' ')

You should avoid dot-notation if your column names are not valid python identifiers and use [] to avoid SyntaxError exception.
