I have a nested loop as shown below,

for num in range(10,20):     #to iterate between 10 to 20
    for i in range(2,num):    #to iterate on the factors of the number
        if num%i == 0:         #to determine the first factor
            j=num/i             #to calculate the second factor
            print '%d equals %d * %d' % (num,i,j)
            break #to move to the next number, the #first FOR
    else:                  # else part of the loop
        print num, 'is a prime number'

when I try to run that in pdb like,

(pdb) for num in range(10,20): for i in range(2,num): if num%i == 0: j=num/I; print '%d equals %d * %d' % (num,i,j); break; else: print num, 'is a prime number'

I get syntax error and I don't know how to run this code in pdb, kindly suggest me how to run it.

The code works for me and no syntax error. probably you are trying to run python 2 code in python 3. try this:

for num in range(10,20):     #to iterate between 10 to 20
    for i in range(2,num):    #to iterate on the factors of the number
        if num%i == 0:         #to determine the first factor
            j=num/i             #to calculate the second factor
            print(num,"equals",i*j)
            break #to move to the next number, the #first FOR
    else:                  # else part of the loop
        print(num, 'is a prime number')

and would be nice if you mention the syntax error you have.

  • (Pdb) **for num in range(10,20): for i in range(2,num): if num%i == 0:j=num/i;print '%d equals %d * %d' % (num,i,j);break; else:print num, 'is a prime number'** _*** SyntaxError: invalid syntax (, line 1)_ – Sunil Joe Dec 10 '18 at 10:52
  • Are you trying to run a Python script from the Python shell? you are not running the code from the correct place. if you are on mac, use the "terminal" application, or from Windows, press Win+R and open `cmd` . navigate to the folder you have file test.py for example which contains this code. and run `python -m pdb test.py` or simply `python test.py` – Yasi Klingler Dec 10 '18 at 19:36
  • im running it in the python shell only I can able to run this script fine **for i in range(5): print("Hello"); print("World"); print(i)** in pdb but could able to do it in the above code – Sunil Joe Dec 11 '18 at 09:51
  • that's the point exactly. look at this: https://stackoverflow.com/questions/13961140/syntax-error-when-using-command-line-in-python and read also the comments below the main answer. – Yasi Klingler Dec 11 '18 at 22:46
