How can omit a column that comparing two columns attributes of two different csv files? : Hej stack overflow coders
I am looking for a solution for this case: expecting a solution from coders of python,  Mysql and MongoDB.

Case :To extend a column (col_F) in file2 values comparing file 1 and file, by line to line and column to column  !!

 - We have one relationship between two files(file1 and file2), which is col_A  

Final results_ extended **file2** with **col_F**
 col_A col_B col_C	col_D	**col_F**
    A1	 B	  C	      D	     **F1**
    A2	 B	  C	      D	     **F2**
    A5	 B	  C	      D	     **F5**
    AZ	 B	  C	      D	     **FZ**
    AX	 B	  C	      D	     **FX**
    A#	 B	  C	      D	     **F#**
    A2	 B	  C	      D	     **F2**

**File1**
col_A 	    **col_F**
    A1	     **F1**
    A2	     **F2**
    A5	     **F5**
    AZ	     **FZ**
    AX	     **FX**
    A#	     **F#**
    A2	     **F2**


**File2** before extension
col_A  col_B	col_C	col_D
  A1	B	     C	     D
  A2	B	     C	     D
  A5	B	     C	     D
  AZ	B	     C	     D
  AX	B	     C	     D
  A#	B	     C	     D
  A2	B	     C	     D
