This mode of Jupyter is indicated by a green line in the leftmost par of an active cell.
Edit
This mode of Jupyter is indicated by a blue line in the leftmost par of an active cell.
Command
What is the shortcut keys to run a code in a Jupyter cell?
Shift + Enter
This is the number that Jupyter assigns to remember which codes are executed first.
Execution Numbers
True or False
Execution numbers are found in the leftmost part of the executed code cells.
False - found in the rightmost part
This is the basic output command of Python.
print()
True or False
print() can’t join plain text with values of numerical expression.
False - print(“1 + 1 =”, 1+1) is possible

- Exponentiation (**)
- Modulo (%)
- Integer Division (//)
It is an external python file that can be imported to a current python file.
Module | import module_name (import math)
True or False
Modules are where functions and other resources are coded in.
True
True or False
Modules allows the user to access a collection of scripts.
False - allows to access a collection of functions
What is the syntax of math functions?
