In flowcharting, several standard symbols are commonly used to represent different types of actions or steps in a process. Here are four primary flowcharting symbols often used in diagrams, regardless of the programming language, including Python:
-
Oval (Start/End Symbol):
- Represents the beginning or end of a flowchart.
- Labelled as "Start" or "End."
-
Rectangle (Process Symbol):
- Indicates a process, action, or instruction to be performed.
- This can be any action, such as a function call or a computation.
-
Diamond (Decision Symbol):
- Represents a decision point where the flow can branch based on a yes/no question or true/false condition.
- It typically leads to two or more paths based on the outcome.
-
Parallelogram (Input/Output Symbol):
- Denotes input to or output from a process, such as reading input from a user or displaying results.
These symbols are widely used to visually represent algorithms and processes in flowcharts, which can be helpful in planning and code design, even in Python.
