can anyone tell what is wrong my code? i got extremely confuse atm
Thanks for helping me out
here is my code:
def arithmetic_arranger(problems):
if len(problems) >= 5:
print ("Error: Too many problems.")
else:
for eq in problems:
if '*' in eq or '/' in eq:
print ('Error: Operator must be '+' or '-'.')
elif '+' in eq:
part = eq.split('+')
strip = [x.strip() for x in part]
print (strip)
longest = 0
short = 0
for num in strip:
if longest < len(num):
longest = len(num)
for num in strip:
if short == 0:
short = len(num)
elif len(num) < short:
short = len(num)
print (longest)
print (short)
print (' '*(len(num)-1), strip[0])
print ('+' + ' '*(longest-(len(num)-1)) + strip[1])
print ('-'*(longest+2))
if True in problems:
print (int(num) + (int(num)))
elif '-' in eq:
part = eq.split('-')
strip = [x.strip() for x in part]
print (strip)
longest = 0
short = 0
for num in strip:
if longest < len(num):
longest = len(num)
for num in strip:
if short == 0:
short = len(num)
elif len(num) < short:
short = len(num)
print (longest)
print (short)
print (' '*(len(num)), strip[0])
print ('+' + ' '*(longest-(len(num)-1)) + strip[1])
print ('-'*(longest+2))
if True in problems:
print (int(num) - (int(num)))
and here is the error:
