Python scripting for beginners

Question

Hello everyone, 
 I am a complete beginner with Python as well as the Python scripting for Plaxis use. 
 I have searched through the web and the Bentley Communities and I couldn't find any topic related to basic scripting such as drawing simple geometries and a simple use of Python in general. 
 Therefore my discussion topic for beginners. 
 My first question is (very basic... I know, but I have no clue how to deal with it...) 
 Why does my script doesn't work (Plaxis 2D) ? 
 from plxscripting.easy import * s_i, g_i = new_server('localhost', 10000, password='>$viK!uhVhx9PB8Ss') 
 g_i.gotostructures() 
 x_min = -10 x_max = 10 y_min = -10 y_max = 10 
 boundaries =[] boundaries.append([x_min,y_min]) boundaries.append([x_max,y_min]) boundaries.append([x_max,y_max]) boundaries.append([x_min,y_max]) 
 g_i.polygon(*boundaries) 
 The error is the following (line 17 is g.i.polygon(*boundaries)) 
 File "testpython1.py", line 17, in <module> g.i.polygon(*boundaries) NameError: name 'g' is not defined 
 
 Thanks for any tips, 
 EDIT : I found the error. Syntax error.

Dear Tomasz, 
 Indeed you have a typo exactly in line 17 and you say g.ipolygon(*boundaries) while it should be g _ i.polygon(*boundaries) 
 Python is very strict with typos and here the g is recognized first as a variable not defined as it is separated with a dot. Of course, you define the variable g_i above. 
 Note that there is documentation about every command that is available and some extra examples provided with our Scripting reference (in V20.04):
