• ## Print map while using lambda in Python 3

• Since lambda x: print(x) is a syntax error in Python < 3, I’m assuming Python 3. That means map returns a generator, meaning to get map to actually call the function on every element of a list, you need to iterate through the resultant generator. Fortunately, this can be done easily: list(map(lambda x:print(x),primes)) Oh, and you can get rid of the lambda too, if you like: list(map(print,primes)) But, at that point you are better off with letting print handle it: print(*primes, sep='\n') NOTE: I said earlier that...

• ## How to Solve Gamma Function

• I. Theoretical Analysis Gamma Function is defined in the following, Using integration by parts, one sees that: From the above calculation，and note that where . If is a positive integer, one can obtain: Appendix: Integral calculus（） \int_{-\infty}^{+\infty}\mathrm{e}^{-(ax^2+bx)}\mathrm{d}x = \int_{-\infty}^{+\infty}\mathrm{e}^{-y^2 + (b^2/4a)}\frac{1}{\sqrt{a}}\mathrm{d}y...

• ## How to Support $$LaTeX{}$$ in GitHub-Pages

• Schrödinger Equation (Math Equation as an example) Note: Original text from stackoverflow page. Since resources online have changed regarding this question, here’s an update on supporting with Github Pages. Note that the closest to Latex rendering without exporting as images and natively supporting it on your Jekyll site would be to use MathJax. MathJax is actually recommended in Jekyllrb docs for math support, with Kramdown, it also converts it from LaTeX to PNG, more details on it here at the Kramdown documentation. Option 1:... Read more
