pd.read_csv('data.csv').head()
pd.read_csv('./data.csv').head()
pd.read_csv('../data/data0.csv').head()

ipynb - jupyter

cd E:/练习册/path_0519
jupyter notebook
print(pd.read_csv('test/data.csv').head())
print(pd.read_csv('data/data0.csv').head())

cd E:/
jupyter notebook

f = open('练习册/path_0519/data/data0.csv')
df = pd.read_csv(f)
f.close()
print(df.head())
