# Thread: I suck at coding need some help

1. ## I suck at coding need some help

Okay, so I have to make a code in python that converts from decimal to binary decimal to hexadecimal and lastly from binary to decimal. This is what I have so far:

Decimal to binary

Spoiler

Spoiler

Binary to decimal
Spoiler

I try to run these and I keep getting syntax errors so the program won't run and I have no idea how to fix them. So could anyone help me correct them not necessarily do them for me but at least give me a better explanation of where the errors are and what to do to fix them any help at all would be appreciated I'm at my wits end here.

Good news is decimal to binary and binary to decimal seem to work fine. The only one that seems to have a problem is decimal to hexadecimal.

Code:
```def decToHex():
#Get number from user
number=int(input("enter a postive number ")#Missing a parenthesis
if(number is<= 0) #What's that is doing there? Also, need a colon
0)#What's this?
print("enter a postive number")
if(number=0) #Should not be an assignment, also a colon
print("the hexadecimal value of 0 equals 0")
else #Colon needed here
hstr=" "
q=number
while(q>0):
if(q%16<10):
hstr=str(q%16)+hstr
elif(q%16==10):
hstr="A"+hstr
elif(q%16==11):
hstr="B"+hstr
elif(q%16==12):
hstr="C"+hstr
elif(q%16==13):
hstr="D"+hstr
elif(q%16==14):
hstr="E"+hstr
elif(q%16==15):
else: #This else probably shouldn't be here
hstr="F"+hstr
q=q//16
print(number, "converted to hexadecimal is " , hstr)```
If you make the changes where I added comments it should compile.

I would also highly recommending downloading a good python IDE - I currently use PyCharm and it works pretty well.
