Need to make a dataframe out of two unequal lists-CodePudding

I have these two lists:

l1 = ['ITEM #', 'UNIT PRICE']
l2 = [['123123', '$10.00'], ['456456', '$250.00'], ['789789', '$6.00']]

I want to create a dataframe like:

ITEM #	UNIT PRICE
123123	$10.00
456456	$250.00
789789	$6.00

Please help with some logical explanation and code! thanks.

CodePudding user response：

Pass both lists to DataFrame constructor, for parameters data and columns:

L1 = ['ITEM #', 'UNIT PRICE'] 
L2 = [['123123', '$10.00'], ['456456', '$250.00'], ['789789', '$6.00']]

df = pd.DataFrame(data=L2, columns=L1)
print (df)
   ITEM # UNIT PRICE
0  123123     $10.00
1  456456    $250.00
2  789789      $6.00

CodePudding user response：

Simply use the DataFrame constructor, passing the second list l2 as data (first parameter by default) and the first list l1 as column names:

l1 = ['ITEM #', 'UNIT PRICE']
l2 = [['123123', '$10.00'], ['456456', '$250.00'], ['789789', '$6.00']]

df = pd.DataFrame(l2, columns=l1)
print(df)

output:

   ITEM # UNIT PRICE
0  123123  $10.00   
1  456456  $250.00  
2  789789  $6.00

Parameters of the DataFrame constructor:

pandas.DataFrame(data=None, index=None, columns=None, dtype=None, copy=None)
