How to get these strings by using return instead of print?

def createSteps(stepCount):
    if stepCount==1:
        for i in reversed(range(1,stepCount+1)):
            print(" "*(( i * 2) - 2), end = '')
            print('+-+')
            print(" " * ((i * 2) - 2), end = '')
            print('| |')
            print(" " * ((i * 2) - 2), end = '')
            print('+-+')
    elif stepCount != 0:
        print(" " * ((stepCount * 2) - 2), end = '')
        print('+-+')
   
        for i in reversed(range(1, stepCount + 1)):
            print(" " * ((i * 2) - 2), end = '')
            print('| |')
            print(" " * ((i * 2) - 4), end = '')
            if i == 1:
                print('+-+')
            else:
                print('+-+-+')

I tried to get the output by using return instead of using print,

for i in reversed(range(1,stepCount+1)):

    a = (" "*(( i * 2) - 2))
    b = ('+-+')
    c = (" " * ((i * 2) - 2))
    d = ('| |')
    e = (" " * ((i * 2) - 2))
    f = ('+-+')
    g = a + b + c + d + e + f
return str(g)

However, the error appears: SyntaxError: 'return' outside function

    Your indentation is inconsistent. Your function must look like this. Note that g is already a string, you don't have to convert it. Also note that you will need to insert the newlines, since you are no longer using print to get that effect.

    def createSteps(stepCount):
    g = []
    for i in range(stepCount,1,-1):
        a = " "*(( i * 2) - 2)
        b = '+-+'
        c = " " * ((i * 2) - 2)
        d = '| |'
        e = " " * ((i * 2) - 2)
        f = '+-+'
        g.extend( [a + b, c + d, e + f] )
    return '\n'.join(g)

  • Sparse Matrix Creation : KeyError: 579 for text datasets

    I am trying to use the make_sparse_matrix function to create a sparse matrix for my text dataset, and I face KeyError: 579. Does anyone has any leads on the root of the error.

    X_train is a DF that contains one single word in each cell, word_index contains all the index of words and y_test stores all labels.

  • Finding part of string in list of strings 
    GCM = ([519,520,521,522,533],[534,525],[526,527,530,531], [4404])

slice = int(str(df["CGM"][row_count])[:3])

    I am looking through a row in a csv file and taking out the number I want. i want the number that starts with the number I have in GCM. since they represent info I want in other columns. this has working fine with the slice function because all the number i wanted started with 3 digits. now that i need to look for any number that starts with 4404 and later on going to probably need to look for 57052 the slice function no longer work.

    is there a way I can, instead of slicing and comparing to list, can take 5 digit number and see if part of it is in list. preferably look for it starting 3 or more same digits. the real point of that part of code is finding out which list in GCM list the number is. it need to be able to have the number 44042 and know that the part of it a care about is in GCM[3], but on the other side do not want it to say that 32519 is in DCM[0] since I only care about number that start with 519 not ends with it.

  • How to forecast a time series out-of-sample using an ARIMA model in Python?

    I have seen similar questions at Stackoverflow. But, either the questions were different enough or if similar, they actually have not been answered. I gather it is something that modelers run into often, and have a challenge solving.

    In my case I am using two variables, one Y and one X with 50 time series sequential observations. They are both random numbers representing % changes (they could be anything you want, their true value does not matter. This is just to set up an example of my coding problem). Here are my basic codes to build this ARIMAX(1,0,0) model.

    import pandas as pd
import statsmodels.api as sm
import statsmodels.formula.api as smf

df = pd.read_excel('/Users/gaetanlion/Google Drive/Python/Arima/df.xlsx', sheet_name = 'final')

from statsmodels.tsa.arima_model import ARIMA
endo = df['y']
exo = df['x']

    Next, I build the ARIMA model, using the first 41 observations

    modelho = sm.tsa.arima.ARIMA(endo.loc[0:40], exo.loc[0:40], order =(1,0,0)).fit()
print(modelho.summary())

    So far everything works just fine.

    Next, I attempt to forecast or predict the next 9 observations out-of-sample. Here I want to use the X values over these 9 observations to predict Y. And, I just can't do it. I am showing below just the one code, that I think gets me the closest to where I need to go.

    modelho.predict(exo.loc[41:49], start = 41, end = 49, dynamic = False)
TypeError: predict() got multiple values for argument 'start'
