I will go for this modification of the original code. file_path = "C:/Users/Rafael/PythonCode/PiDigits.txt" with open(file_path) as a: b = a.read() get_year = input("What year were you born? ") count = 0 b= '3'+b[2:] n = len(b) for i in range(n-4): if b[i:i+4] == get_year: count

Modifying the code as shown below may work. file_path = "C:/Users/Rafael/PythonCode/PiDigits.txt" with open(file_path) as a: b = a.read() get_year = input("What year were you born? ") count = 0 for year in b: if get_year in b: count += 1 print("Your birth date occurs %s times in

I wrote a program which checks if PI (first one million digits) contains a person's birth year. file_path = "C:/Users/Rafael/PythonCode/PiDigits.txt" with open (file_path) as a: b = a.read() get_year = input("What year were you born? ") for year in b: if get_year in b:

[Tutor] Asking about Run python script at Startup

Hi guys, I do not know how to run my python 3 script after my PI2 finished startup. I searched about it on some websites, and I feel so confused. Anyone know the easy way to run at startup with escape plan?. I am afraid that it will be a looping trap if I do not have escape plan :) Thank you

Re: [Tutor] Euclidean Distances between Atoms in a Molecule.

Dr. Molnar: This might be your solution: >>> import numpy >>> a = numpy.array((-3.265636, 0.198894, 0.090858)) >>> b = numpy.array((-1.307161, 1.522212, 1.003463)) >>> dist = numpy.linalg.norm(a-b) >>> dist 2.5337013913983633 >>> Qiao Qiao > On Apr 2, 2017, at 1:41 PM, Stephen P. Molnar

Re: [Tutor] Euclidean Distances between Atoms in a Molecule.

Hi Stephen- The `scipy.spatial.distance` module (part of the SciPy package) contains what you will need -- specifically, the `scipy.spatial.distance.pdist` function, which takes a matrix of m observations in n-dimensional space, and returns a condensed distance matrix as described in
