Please what is wrong with the range

Question

Why does it give me error
def factors(a):
list=[]
for num in range(a+1)
if a % num == 0:
list.append (num)
return list
a = input('Enter a number: ')
print(factors(a))
for num in factors(a)
print(num)
print(num,end=",")

Answer 1

def factors(a):
list=[]
for num in range(a+1) #missing : here, and also you must start from 1 so use range(1, a+1) otherwise a%0 raise error.
if a % num == 0:
list.append (num)
return list #ident this out of loop else it only return 1 element of list

a = input('Enter a number: ') #input defaultly is of string type, convert input to int type
print(factors(a))
for num in factors(a) # missing : here
print(num) # why this?
print(num,end=",")

# read comments, hope those helps to correct program..
