How to use the value in a variable as name to create a panda data frame?

In [182]: colname

Out[182]: ‘col1’

In [183]: x= ‘df_’ + colname

In [184]: x

Out[184]: ‘df_col1’

May I know how to create a new pandas data frame with x, such that the new data frame’s name would be df_col1

Answer

You can use the locals() function as given below,

>>> mydf
  col_A  col_B
0  1      4    
1  2      5    
2  3      6    
>>> colname = 'col1'
>>> locals()[f'df_{colname}'] = mydf.col_A
>>> df_col1
    0    1
    1    2
    2    3
Name: col_A, dtype: int64
