IIRC, the BASIC mid$ function is mid(string, start, length), where the
starting index is 1-based. The Python equivalent is
string[start-1:start-1+length], so these two lines would convert to
location = [oRawEDID(i)[54:72], oRawEDID(i)[72:90]]

The "chr" function is the same in Python as in VB. But unlike VB, you
can use literals for special characters.
strSerFind = '\x00\x00\x00\xFF'

In python, the string concatenation operator is "+" instead of "&".
However, this line can be written more concisely as:
tmpver = "%c.%c" % (48 + tmpEDIDMajorVer, 48 + tmpEDIDRev)
But for single-digit integers, chr(48+n) is just an obscure way of
writing str(n), so what it really means is:
tmpver = "%s.%s" % (tmpEDIDMajorVer, tmpEDIDRev)

VB's "and" operator is a bitwise operator; the "if" statement is
testing whether bit 4 is set in Byte1. The Python equivalent is
if Byte1 & 0x10:
Char1 += 4
