# Thursday April 27th

## Kata solved:

• Greeting with name, time (in Python)
``````def greetings(time, name):
// if either time or name is None, returns statement
if (time == None) or (name == None):
return "Hey dude greet someone"
else:
// returns "Good" + time + name
return "Good {} {}".format(time, name)
//why am I writing JavaScript comments in Python? :)

``````

## Working on

• Programming for Correctness

## When the Struggle is Real

• I couldn’t find this symbol (shown below -> specifically the subscripted “E”). The guy teaching refers to it as “Expression” but I couldn’t find it on Math Stack Exchange or in LaTeX documentation. So I tweeted and asked my Computational Mathematics friend about it. We’ll see.

Yup…this little guy here in the Subscript.

Solved it by using

``````\${R}_{\mathpzc{E}}^{k}\$ \$>\$
``````

## Update

• Got back from drinking with German scientists at JPL, and was informed that it is an old-school Math-Cal symbol. There is a library using Lucida Calligraphy that can duplicate it. See this conversation on Math Stack Exchange. Yay. Problem solved!

## Random

• I attend the JPL German Club once a month. It’s really fun! It’s tonight, so looking forward to it.

• I learned how to insert a therefore in LaTeX :) I enjoy hanging out with my mentor because he also deeply appreciates (and has been using for many years) LaTeX. I really enjoy using it and hope to get better at it and use it professionally as long as I can (or even just for fun).
