Add trailing zeros to field

CCWeedcontrol

I have a table BuildingTable with building info. There is a field called "Build_num" with characters like B37828 or B2898101 or R29499010C or R29499010C2 that i need to join to a shapefile but the the Shapefile BuildNum has a max of 11 characters like so B3782800000 or B2898101000. so i can't join the table to shapefile.

How can update the BuildingTable field "Build_num" to add trailing zeros to that field?

I tried the following, i added a new filed to insert the new Build numbers with the trailing zeros but nothing happened.

import arcpy

fc = "BluidingPermitsTable"
fields = ('Build_num', 'BuildNum')
with arcpy.da.UpdateCursor(fc, fields) as cursor:
    for row in cursor:
        if row[0] <= 11:
            row[1] = '0' + str(row[0])
            cursor.updateRow(row)

Thanks.

To add trailing zeros, try something like:

BuildNum <SPAN class="operator token">=</SPAN> <SPAN class="string token">"B37828"</SPAN>
<SPAN class="keyword token">print</SPAN> BuildNum<SPAN class="punctuation token">.</SPAN>ljust<SPAN class="punctuation token">(</SPAN><SPAN class="number token">11</SPAN><SPAN class="punctuation token">,</SPAN><SPAN class="string token">'0'</SPAN><SPAN class="punctuation token">)</SPAN>

<SPAN class="keyword token">print</SPAN> <SPAN class="string token">"B2898101"</SPAN><SPAN class="punctuation token">.</SPAN>ljust<SPAN class="punctuation token">(</SPAN><SPAN class="number token">11</SPAN><SPAN class="punctuation token">,</SPAN><SPAN class="string token">'0'</SPAN><SPAN class="punctuation token">)</SPAN>

<SPAN class="comment token"># for your code</SPAN>
row<SPAN class="punctuation token">[</SPAN><SPAN class="number token">1</SPAN><SPAN class="punctuation token">]</SPAN> <SPAN class="operator token">=</SPAN> row<SPAN class="punctuation token">[</SPAN><SPAN class="number token">0</SPAN><SPAN class="punctuation token">]</SPAN><SPAN class="punctuation token">.</SPAN>ljust<SPAN class="punctuation token">(</SPAN><SPAN class="number token">11</SPAN><SPAN class="punctuation token">,</SPAN><SPAN class="string token">'0'</SPAN><SPAN class="punctuation token">)</SPAN>
