Displaying a Variable's Value

To output a variable's value, use the print statement. This code:

# Declare a variable
design_name = "pt_demo"

# Inspecting a single variable
print("Design: " + design_name)

# Another way of inspecting a single variable
print("Design: {}".format(design_name))

# Yet another way of inspecting a single variable
print(f"Design: {design_name}")

Prints this output to the Python console:

Design: pt_demo
Design: pt_demo
Design: pt_demo

If you want to print a map, the built-in Python function, pprint(), nicely prints out the content. This code:

# Declare a dict of pin name and its information
pin_data = {
    "resetn":"Global control reset pin",
    "Oclk":"Output clock pin name"
}

# Inspecting a dict
import pprint             # This can be done at the top as well
pprint.pprint(pin_data)

Prints this result to the Python console:

{'Oclk': 'Output clock pin name', 'resetn': 'Global control reset pin'}
