In this method you will not need to write more number of lines.

list = [int(i) for i in input()]

for input`123456789` you will get `[1,2,3,4,5,6,7,8,9]` | `list(number)` will convert the string to a list of characters. It sounds like you need to assign the result back to `number` though, like this:

74,603 | The numerical coincidence that triggered Dirac to postulate his Large Number Hypothesis can be summarized by expressing the proton-electron gravitational angular momentum in units $\hbar c$:

Mass pion ~ (hn^2*Ho/G*c)^1/3 .
where
hn = h/2π = reduced planck constant.
Ho = Hubble constant.
G = Newton constant.
c = light speed.
It is very surprised. Why pion mass is related to Hubble constant ? /1/
The well known Weinberg Relation for pion mass is calculated and explained /2/.

150,479 | I'm working through a contour integral question, which is rounded off by finding the integral:
$$\int^{\infty}\_{0} \frac{x-\sin(x)}{x^3} dx$$

] | There's a StrictDelimiter property on the TStringList. Set it to True and it will only parse on the delimiter, not the spaces. | That's standard, documented behavior of the [`TStrings.DelimitedText`](http://docwiki.embarcadero.com/VCL/en/Classes.TStrings.DelimitedText) property. You want to set the [`StrictDelimiter`](http://docwiki.embarcadero.com/VCL/en/Classes.TStrings.StrictDelimiter) property to *true* to disable that behavior. |
