Study Notes
Functions in Python
- The
int
function is used to convert user input into an integer data type. - The
input
function is used to get user input, which is a string by default, and display a prompt to the user. - The program asks the user to enter a value, which is then assigned to a variable.
- Assigning the user's value to a variable, such as
temp
, is used to store the input value for further processing.
IDLE
- When saving a file in IDLE, it should be appended with a
.py
extension. - IDLE makes the program easier to read by providing syntax highlighting and formatting.
- The shell window in IDLE is used to run the program and display the output.
Running the Program
- The
Run Module
option should be chosen in IDLE when the program is ready to be executed. - After choosing
Run Module
, IDLE will ask the user to save the file if it has not been saved before. - The
eval
function is used to parse the expression passed to it and execute Python code within the program.
Print Function
- The primary function of the
print
function is to display output to the screen. - The
sep
argument in theprint
function is used to specify a separator between values, such as:
or##
. - The
end
argument in theprint
function is used to specify what should be printed at the end of the line, such as a newline or a space.
Best Practices
- It is important to use lowercase in Python statements as Python is case-sensitive.
- Python relies on precise placement of commas and parentheses to avoid syntax errors.
- If you run a program with input statements and nothing seems to be happening, it may be because the program is waiting for user input.
