Python | sympy.compositepi() method Last Updated : 27 Aug, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report With the help of sympy.compositepi() method, we can find the number of composite numbers less than or equal to a given number. Syntax: compositepi(n) Parameter: n - It denotes the number up to which the count of composite number is calculated. Returns: Returns the number of composite numbers less than or equal to n. Example #1: Python3 # import compositepi() method from sympy from sympy import compositepi n = 10 # Use compositepi() method count_composites = compositepi(n) print("The number of composites numbers less than or equal to {} is {}".format(n, count_composites)) Output: The number of composites numbers less than or equal to 10 is 5 Example #2: Python3 # import compositepi() method from sympy from sympy import compositepi n = 100 # Use compositepi() method count_composites = compositepi(n) print("The number of composites numbers less than or equal to {} is {}".format(n, count_composites)) Output: The number of composites numbers less than or equal to 100 is 74 Comment More infoAdvertise with us Next Article Python | sympy.compositepi() method R rupesh_rao Follow Improve Article Tags : Python SymPy Practice Tags : python Similar Reads Python | sympy.composite() method With the help of sympy.composite() method, we can find the nth composite number, with the composite number indexed as composite(1) = 4, composite(2) = 6, etc. Syntax: composite(n) Parameter: n - It denotes the nth composite number. Returns: Returns the nth composite number. Example #1: Python3 # imp 1 min read Python | sympy.is_composite method With the help of sympy.is_composite method, we can check whether element is composite or not this method will return the boolean value i.e True or False. Syntax : sympy.is_composite Return : Return True if composite else False. Example #1 : In this example we can see that by using sympy.is_composite 1 min read Python | sympy.compare() method With the help of sympy.compare() method, we can compare the variables and it will return 3 values i.e -1 for smaller, 0 for equal and 1 for greater by using sympy.compare() method. Syntax : sympy.compare() Return : Return the value of comparison i.e -1, 0, 1. Example #1 : In this example we can see 1 min read Python | Sympy Circle() method In Simpy, the function Circle() is used to make circle from a center and a radius, from three non-collinear points, or the equation of a circle. Syntax: Circle() Parameters: center : Point and radius : number or sympy expression or points : sequence of three Points or equation : equation of a circle 1 min read Python PIL | composite() method PIL is the Python Imaging Library which provides the python interpreter with image editing capabilities. PIL.Image.composite() method creates composite image by blending images using a transparency mask. Here, mask is another image which remains transparent when composite together.
