python speed code example

Example 1: internet speed test with python

#first install the mosule
pip install speedtest-cli
#make sure evry thing is good
speedtest-cli --version
#speed test
speedtest-cli
#in bytes
speedtest-cli --bytes
#if you want a picture to shate 
speedtest-cli --share

Example 2: how to speed up python code

Speed Up Compile Time:

1. Use correct data structure
2. Try to minimize use of for loop
3. Use less global variables

Example 3: type python fast

def f(double x):
    return x ** 2 - x


def integrate_f(double a, double b, int N):
    cdef int i
    cdef double s, dx
    s = 0
    dx = (b - a) / N
    for i in range(N):
        s += f(a + i * dx)
    return s * dx
