Using .append() with list vs dataframe

[Axel_Erfurt]

append is deprecated

import pandas as pd
df = pd.DataFrame([['blue', 3], ['red', 8], ['green', 0]])
print(df)

df2 = pd.DataFrame([['grey',12]])
df = pd.concat([df, df2], ignore_index=True)
print(df)

Output:
       0  1
0   blue  3
1    red  8
2  green  0
       0   1
0   blue   3
1    red   8
2  green   0
3   grey  12
