how can you define a periodic function in python, e.g. the "sawtooth" function?

f(x) = x, for –π < x < π and 2-pi periodically continued on IR

Can you do this with a lambda function?

You can make use of decorators:

```def periodically_continued(a, b):
interval = b - a
return lambda f: lambda x: f((x - a) % interval + a)

@periodically_continued(-1, 1)
def f(x):
return x

g = periodically_continued(0, 1)(lambda x: -x)

assert f(2.5) == 0.5
assert g(2.5) == -0.5
```

How to plot periodic function's graphic?, What about this? This defines a rather general function myperiodic that translate a normal function to periodic form, the second parameter {val, min, max} specify� An elegant way to run periodic tasks in python. sankalp jonna. Follow. With this approach, if the program is killed in between, the function foo() would be killed abruptly. Also if you want to

as a normal function you can use modulo (`%`) also with float:

```from math import pi

def f(x):
return (x+pi) % (2*pi) - pi
```

this easily translates to a lambda expression:

```lambda x: (x+pi) % (2*pi) - pi
```

Simple example running python periodic python functions � GitHub, Simple example running python periodic python functions. periodic.py. import asyncio. from collections import namedtuple. from functools import wraps. tasks = []. Here are a few minor suggestions for squeezing out a little extra speed in your function. In the Cython code you wrote above you use the Python abs and int function. This induces coercion of your fast C-data types to slow Python-data types.

You could write a function that takes a function and a period, and returns a function:

```import math

def periodic_function(func, period, offset):
return lambda x: func( ((x - offset) % period ) + offset )
```

and use that then:

```sawtooth = periodic_function(lambda x: x, 2*math.pi, math.pi)
```

defining periodic functions, I guess I can do something like while x>2: x = x-4, etc., but my real question is, can I define such a function symbolically rather than as a Python� This tutorial will guide you to learn how to define a function inside a function in Python. You can also name it a nested function. Introduction: Using a function inside a function has many uses. We call it nested function and we define it as we define nested loops. It is useful to keep data secure from outside things.

A very simple way is to limit the inputs to the first period. Iteratively remove one period until the input falls within the defined values. For example the following example gives a square wave with period 2*pi.

```def f(t):
while t>2*np.pi:
t=t-2*np.pi
if 0.0 <= t <=np.pi:
return 1.0
else:
return -1.0
```

An elegant way to run periodic tasks in python, With python, there are several ways of creating and executing a periodic task. What are Python Functions? Python Functions are a convenient way to divide our code into useful blocks that can be reused and save lots of time in coding. How to define functions in Python? Creating a function in Python is a simple and easy task. To define a Python function, the “def” block keyword used.

repeating plot of Periodic Function, How do you plot in Maple 17 a function like f(t)= e-t for -1<=t<=1, with a Period of 2? I know that in "The fourier Series" package back in Maple� p. Learning how to define a function in Python is one of the most important steps to mastering the language. Functions are blocks of code that perform a specific task and can be “called” from

Generating periodic signals - Python Data Analysis, Normally, we would simulate a periodic signal using trigonometric functions such as a sine function.

• plz explain `2-pi periodically continued on IR`
• +1 Nice idea! `expense` is an odd word to use, though. Did you mean `expanse`? `extent`? (I'd probably just call it `periodic`, or perhaps `periodic_on`.)
• You also want to replace `x % interval` with `(x - a) % interval`, I think.
• You don't need the Python 3 disclaimer: `%` works for floating-point numbers in both Python 2 and Python 3. And I think you want `(x + pi) % (2*pi) - pi` to get the right result.
