Introduction Python - Basic Syntax

In SimLab, we use Python as one of the two scripting languages for automation.

Print Statement

print("SimLab Automation")
MeshSize = 3
print("Mesh Size =", MeshSize)

Output
SimLab Automation
Mesh Size = 3

Comments start with a # and extend to the end of line. For multi-line comment insert # at each line.

# This is a comment

In python interpreter, you can simply type the expression directly and it will write out the value.

3*2

Output
6

Python uses indentation to identify the block of the code.

There is no explicit command for declaring a variable. It is created the moment a value is assigned to it.

GroupName = "Fillet_Faces"
NumLayers = 3
MeshSize = 1.5

You can also assign values in a line as below:

GroupName, NumLayers, MeshSize = "Fillet_Faces", 3, 1.5

To assign the same value to multiple variables

x = y = z = 0

To find type of any object use type() function.

GroupName, NumLayers, MeshSize = "Fillet_Faces", 3, 1.5
print(type(GroupName))
print(type(NumLayers))
print(type(MeshSize))

 Output
<class 'str'>
<class 'int'>
<class 'float'>
