Increasing the value of x in a for loop-CodePudding

I'm trying to edit the value of bigalgs, but when I actually print the value of it, it just spits the initial value of bigalgs, which is 0. Why is this happening? Am I increasing the value of bigalgs the wrong way? I think it was by simply using the sign... Maybe the for loop? Help!

(for reference, alg here means algorism)


class scinoteConvert:
    def __init__(self, num):
    
        alglog = []
        alglist = []
        bigalgs = 0
        num = str(num)

        for alg in num:
            alglist.append(alg)

        for alg in alglist:
            if int(alg) < 1:
                alglog.append(True)
            else:
                alglog.append(False)
                print(bigalgs)
                bigalgs   1

        print(alglist, alglog, bigalgs)

input = int(input('Insert num: '))

if input < 1:
    exit('Error! Cannot calculate negative values!')

scinoteConvert(input)

In the code you need to write : bigalgs = bigalgs 1 in this way the value of the variable bigalgs will be incremented by 1. when written bigalgs 1 the value of bigalgs doesnt change

CodePudding user response：

Your code is correct , But you should be in the syntax to add 1

bigalgs  = 1

the code will become :

class scinoteConvert:
def __init__(self, num):

    alglog = []
    alglist = []
    bigalgs = 0
    num = str(num)

    for alg in num:
        alglist.append(alg)

    for alg in alglist:
        if int(alg) < 1:
            alglog.append(True)
        else:
            alglog.append(False)
            print(bigalgs)
            bigalgs  = 1

    print(alglist, alglog, bigalgs)



input = int(input('Insert num: '))

if input < 1:
    exit('Error! Cannot calculate negative values!')

scinoteConvert(input)

I think you should write bigalgs = bigalgs 1 instead of bigalgs 1. When you write bigalgs 1 you do not change the value of the variable.

CodePudding user response：

You have to use = 1, so bigalgs = 1, so your solution is

bigalgs =  bigalgs  =1

because =1 is for incrementing a variable by one in a loop, so modify the object in-place if it's mutable. You only wrote bigalgs 1.

Here's how to increase the bigals value the right way. That way when you print the bigals value, you shouldn't spit out its initial value 0.

class scinoteConvert:
    def __init__(self, num):
    
        alglog = []
        alglist = []
        bigalgs = 0
        num = str(num)

        for alg in num:
            alglist.append(alg)

        for alg in alglist:
            if int(alg) < 1:
                alglog.append(True)
            else:
                alglog.append(False)
                print(bigalgs)
                bigalgs =  bigalgs  =1

        print(alglist, alglog, bigalgs)

input = int(input('Insert num: '))

if input < 1:
    exit('Error! Cannot calculate negative values!')
