#or clone it from github and run the setup.py file
#git clone https://github.com/facebookresearch/fastText.git
#then run the setup.py file

import fasttext
# Skipgram model :
model = fasttext.train_unsupervised('data.txt', model='skipgram')
# or, cbow model :
model = fasttext.train_unsupervised('data.txt', model='cbow')

Example 2: what is pypy

pypy is a compilable version of cpython

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
