Block programming in Python can refer to two concepts:
Visual block coding – using drag-and-drop blocks that translate into Python code.
Code blocks – logical groupings of Python statements defined by indentation.
Visual Block Coding is popular for beginners and kids. Tools like OneCompiler or Scratch-style editors let you drag and drop colorful blocks to create logic, which is then converted into Python. For example, a multiplication table block sequence:
# Python code generated from visual blocksprint('2 Table')for i in range(1, 11):result = i * 2print(f'2 × {i} = {result}')print('Done!')Copied!✕CopyThis approach removes syntax barriers and focuses on logic building.
Code Blocks in Python are defined by indentation rather than braces {}. They group statements for control flow, functions, classes, and exception handling.
Examples of Python block types:
Function Block
def greet(name):print(f"Hello, {name}!")Copied!✕CopyConditional Block
