python - Adding line breaks in ipython

If introduce a for loop in iPython, or any multi-line command, how do I go back and add lines to it? I ran this:

for row in table.find_all('tr'):
    cells = row.find_all('td')
    for c,cell in enumerate(cells):
        print c,":",cell.get_text().strip()
    try:
        this = cells[0]
        that = cells[1]
        the_docket = cells[2]
        other_thign = cells[3]
        jumble = re.sub('s+',' ',str(cells[5])).strip()            
    except:
        "Nope"

And realized I need to add a line to it, but I can't just hit "enter" in iPython, b/c that runs the command. So can I edit that multi-line command w/in iPython?

Been suffering this problem for a while. I just found that when using Ctrl-qCtrl-j (That's lowercase Q, J, no need to hold the shift key) will add a linefeed to an existing IPython edit session.

for li in some_list: print(li)    

Moving the cursor after the colon and pressing Ctrl-qCtrl-j

for li in some_list:
print(li)

IPython: 5.2.1, iTerm2: 3.0.15, macOS: 10.12.6
