3.7 Experimental seeking factor 10

When stored in a string to create a variable Str, result = '', need to be stored enters
a result + = str (i) # remember data transfer type strong

result=''
sum1=0
i=1
while i<=10:
    if 10%i==0:
        result+=str(i)+','
        sum1=sum1+i
    i+=1
print('10的所有因数为%s 因数累加和为%d'%(result,sum1))
