And that’s day two in the pocket. The Python hour was spent looking at data types, calculations, manipulations and fstrings.
And that's day 2/100 of #100daysofcodechallenge in the books. Worked with numbers, calculations, datatypes and ftypes today #python Will write my report this evening! #vCommunity

Remark: Besides the Python course I also spend several hours diving into Powershell code for an application that I have been working on for a while.
Notes taken:
[] is get x character from string
print("Hello"[2]) get's first l
integers
use _ to make more readable
123_456_789 is read as 123456789
floating
float = floating point number
3.14159
boolean True or False (capiutal T and capital F)
bool = True
type checking
type(var_name)
print(type(var_name))
force string
str(var_name)
int(var_name)
calculations
()
** power off (2 to the power of 4)
* / (Order of written down)
+ - (Order of written down)
print(3 * 3 + 3 / 3 - 3) = 7
round(int(var_name) / 3, 2) the , 2 sets amount of digits
floor = // (8 // 3) = 2
calc var_name += 1
f-string f"fsafsa"
can be used to combine multiple types in a string
print(f"blabla {var_number}")
