Python PCEP
python - correct answer ✔not meant for low level programming
emphasizes code readability
works in any environment
lots of libraries
many frameworks
interpreter - correct answer ✔-reads from top to bottom, left to right, with
exceptions
-performs instruction validation
-results returned per instruction, in sequential order
-can be run from CLI using py or installed in the IDE
-execution takes more time. instruction needs to be compiled real time.
-code can be executed in any environment
-code is needed each time the program is executed
compiler - correct answer ✔-takes more time but code execution is faster
-code is compiled for a specific operating system
-source code is typically unavailable and compiled data can be read
-once binary code is compiled, source code no longer needed
python 2 - correct answer ✔legacy code
older libraries not forward-compatible
ASCII
rounds calc to nearest whole number
,print "hello"
python 3 - correct answer ✔new in 2020
strings in unicode
calcs not auto rounded
print ("Hello")
python types - correct answer ✔-cpython original
-jython designed to run on Java platform
-ironpython an implementation of python integrated with .net platform
installation process - correct answer ✔windows - installed in the AppData
directory
download from python site
interpreter launched from CLI either by py or python3
IDE - correct answer ✔integrated development environment
program dedicated to specific software development
easier than CLI
pycharm
IDLE - correct answer ✔integrated development and learning environment
2 main windows: shell and editing
cross platform works on windows, unix, and macOS
pycharm - correct answer ✔simple windows installation with some config
, allows virtual environment to manage all project settings
console informs developer if there are mistakes
string - correct answer ✔a sequence of characters enclosed in quotation
marks
integer - correct answer ✔All whole numbers (both positive and negative)
and zero.
float - correct answer ✔A native type representing rational numbers to limited
precision. Real numbers. decimals.
boolean - correct answer ✔A single value of either TRUE or FALSE. yes/no
hashtag - correct answer ✔renders a line a comment #this is a comment
(""") - correct answer ✔used in the beginning and end of a multiline
comments
"""
This is,
a docstring
comment

(" " ) - correct answer ✔used in print ( )
print("Hello World")
#prints Hello World
