Which function is there in Python equivalent to Val() in VB6?

Question

I'm converting some programs from Visual Basic 6.0 to Python, and I'm stuck in one line in VB.

Visual Basic code:

bAddStart = "100"
bNoOfBytes = "94"
MeterId = 1

Data = Chr(MeterId) + Chr(3) + Chr(Val(bAddStart) \ 256) + Chr(Val(bAddStart) Mod 256) + Chr(0) + Chr(Val(bNoOfBytes))

For the function Chr in VB I'm using chr() in Python.
For the Val function, which is a similar function in Python?

Answer 1

try int(bNoOfBytes)

e.g: chr(int("65")) will return A.

Answer 2

There is no inbuilt function in python that is equivalent to Val(). You will have to implement your own function. I used this code when I ran into a similar problem before -

def val(data):
    y=0
    nst=""
    dlist = ['0','1', '2', '3', '4', '5', '6', '7', '8', '9']
    for x in data:
        for i in dlist:
            if x == i:
                nst=nst+x
    n=len(nst)
    dcont=n
    acum=0
    for z in range(n):
        y=0
        for i in dlist:
            if nst[z] == i:
                d=y
                mult=1
                dcont=dcont-1
                for j in range(dcont):
                    mult=mult*10
                acum=acum+(d*mult)
            y=y+1

    return acum

Answer 3

if we use int() function as below, you will get the perfect answer.

    str_no = "12345"
    no = int(str_no) * 1
    print(no)
    print(no + 1)
