I am checking if a dataframe is empty or not but i want to do this in 1 line of code as i am checking many dataframe’s and don’t want to repeat the same code again as it becomes chunky. example is below. great if anyone can help

if not df.empty:
   df['test_col'] = np.nan
else:
   print('data is empty')

>Solution :

you can do a for loop:

list_of_dfs=[df1,df2,df3] # there can be any number of dfs
for x in list_of_dfs:
  if not x.empty:
   x['test_col'] = np.nan
  else:
   print('data is empty')
