Python: find the minimum in all rows

I am using Biopython to process an alignment in fasta format. I need to slice the sequences where there is the first stop codon. So I divided my alignment in codons and found the stop.
I then found the first codon position using enumerate().
But I found the minimum for each row. However I need to find the minimum (storing it where it won't be reset when it does the next row), determine which of those is smallest. So that I can slice all the sequences in the same place.

pstop gives me the min for each row and I want to get the min of those min
to slice everything according to that min.
Thanks you very much for your help!

```ddi_dma_devalign(9F)					   Kernel Functions for Drivers 				      ddi_dma_devalign(9F)

NAME
ddi_dma_devalign - find DMA mapping alignment and minimum transfer size

SYNOPSIS
#include <sys/conf.h>
#include <sys/ddi.h>
#include <sys/sunddi.h>

int ddi_dma_devalign(ddi_dma_handle_t handle, uint_t *alignment, uint_t *minxfr);

INTERFACE LEVEL
Solaris DDI specific (Solaris DDI).

PARAMETERS
handle	       The DMA handle filled in by a successful call to ddi_dma_setup(9F).

alignment       A  pointer  to an unsigned integer to be filled in with the minimum required alignment for DMA. The alignment is guaranteed
to be a power of two.

minxfr	       A pointer to an	unsigned  integer  to  be  filled  in  with  the  minimum  effective  transfer	size  (see  ddi_iomin(9F),
ddi_dma_lim_sparc(9S) and ddi_dma_lim_x86(9S)).	This also is guaranteed to be a power of two.

DESCRIPTION
ddi_dma_devalign()  determines  after  a successful DMA mapping (see ddi_dma_setup(9F)) the minimum required data alignment and minimum DMA
transfer size.

RETURN VALUES
ddi_dma_devalign() returns:

DDI_SUCCESS     The alignment and minxfr values have been filled.

DDI_FAILURE     The handle was illegal.

CONTEXT
ddi_dma_devalign() can be called from user or interrupt context.
