Concatenate strings to existing variables

Hi all,

I have a for loop in place which I would like to use to trigger an action for each of my variables, something similar to an eval() in javascript.
What I am looking for from the below is if setpinnumberorall == all & setpinshighorlow == high, then:
pinout2.write(1)
pinout3.write(1)
pinout4.write(1)
pinout5.write(1)
etc... to be executed

Code:

    global pinout2
    global pinout3
    global pinout4
    global pinout5
    global pinout6
    global pinout7
    global pinout8
    global pinout9
    global pinout10
    global pinout11
    setpinnumberorall = request.args.get('setpinsmessage')
    setpinshighorlow = request.args.get('setpinmessagehighorlow')
    if setpinnumberorall == "all":
	if setpinshighorlow == "high":
	    for x in range(2, 12):
		digitalpintomodify = "pinout" + x
		print eval(digitalpintomodify)
		eval(digitalpintomodify).write(1)
		
	else:
	    for x in range(2, 12):
		print x + 2
		digitalpintomodify = "pinout" + x
		print eval(digitalpintomodify)
		eval(digitalpintomodify).write(0)
    else:
	print setpinnumberorall

Thanks

Globals are not necessary here. You can store the function calls in a list instead of jumping through hoops.

Code:

def test_funct1():
    print "test_funct one executed"

def test_funct2():
    print "test_funct two executed"

some_list = [test_funct1(), test_funct2(), test_funct1()]
for ctr in range(len(some_list)):
    some_list[ctr]

or use one function to call the others

Code:

def test_funct1():
    print "test_funct one executed"
def test_funct2():
    print "test_funct two executed"

def call_all():
    test_funct1()
    test_funct2()

call_all()

Finally, there is redundant code

Code:

    if setpinnumberorall == "all":
        el = 0
	if setpinshighorlow == "high":
            el = 1
        for x in range(2, 12):
		digitalpintomodify = "pinout" + x
		print eval(digitalpintomodify)
		eval(digitalpintomodify).write(el)
