CodePudding user response:

 import pandas as pd 
Df=pd DataFrame (columns=(' lib ', 'qty1', 'qty2)) 
Df=df append ([{' qty1 ', 10.0 'qty2:98}], ignore_index=True) 
Print (df)

reference 1/f, happy pigs response:

 import pandas as pd 
Df=pd DataFrame (columns=(' lib ', 'qty1', 'qty2)) 
Df=df append ([{' qty1 ', 10.0 'qty2:98}], ignore_index=True) 
Print (df)
