python - How to pass variables into next function without using global -

-

i'm looking how can take variables i've saved next function. illustrate mean, i'm getting latest version number online such:

try:      webversion = urllib2.urlopen(          "http://www." + server + "/version").read().rstrip()      if webversion > version:           update_files()      elif version >= webversion:           print "[system] have latest version: v." + version

in update_files() function, take variable i've gained (webversion , possibly version) on next function.

i'm thinking of setting variable global:

try:      global webversion      webversion = urllib2.urlopen(          "http://www." + server + "/version").read().rstrip()      if webversion > version:           update_files()      elif version >= webversion:           print "[system] have latest version: v." + version

is there better way/smarter this?

just pass arguments function:

function definition:

def update_files(webversion, version):     # ... function execution

and code:

try:      # global webversion don't need      webversion = urllib2.urlopen("http://www." + server + "/version").read().rstrip()      if webversion > version:           update_files(webversion, version)      elif version >= webversion:           print "[system] have latest version: v." + version #and careful add except, try! except:     print("error!")

SoapUI on windows 10 - high DPI/4K scaling issue -

-
Image
soapui doesn't seem dpi-aware , displays small on high dpi screen (tiny text , buttons). other applications running fine (screen resolution 3840 x 2160). version : soapui 5.1.2 os : windows 10 i have tried: configure soapui run "disable display scaling on high dpi settings" - parts of soapui looking bigger , don't display (image) changing resolution changing font size (preferences > editor settings > select font...) therefore assume, soapui pretends dpi-aware, not scale itself. have same issue? this workaround until developers round making version dpi-aware. step 1: add registry key hkey_local_machine\software\microsoft\windows\currentversion\sidebyside\preferexternalmanifest (dword) 1 step 2: add manifest file 'soapui-5.2.1.exe.manifest' in same directory 'soapui-5.2.1.exe' content of manifest file: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <assembly xml
