Suppress Scientific Notation in Numpy When Creating Array From Nested List

Question

I have a nested Python list that looks like the following:

my_list = [[3.74, 5162, 13683628846.64, 12783387559.86, 1.81],
 [9.55, 116, 189688622.37, 26033226         


        

Answer 1

You could write a function that converts a scientific notation to regular, something like

def sc2std(x):
    s = str(x)
    if 'e' in s:
        num,ex = s.split('e')
        if '-' in num:
            negprefix = '-'
        else:
            negprefix = ''
        num = num.replace('-','')
        if '.' in num:
            dotlocation = num.index('.')
        else:
            dotlocation = len(num)
        newdotlocation = dotlocation + int(ex)
        num = num.replace('.','')
        if (newdotlocation < 1):
            return negprefix+'0.'+'0'*(-newdotlocation)+num
        if (newdotlocation > len(num)):
            return negprefix+ num + '0'*(newdotlocation - len(num))+'.0'
        return negprefix + num[:newdotlocation] + '.' + num[newdotlocation:]
    else:
        return s
