Study Notes
Function Calls and Parameters
- A function can be called with arguments, which are values passed to the function.
- Arguments are assigned to parameters, which are variables defined in the function definition.
Return Values
- A function can return a value, which can be used in other parts of the program.
- The
return
statement is used to specify the value that the function should return. - If a function does not contain a
return
statement, it is considered to returnNone
. - The
return
statement can also be used in conditional statements to return different values based on conditions.
Math Functions
math.fsum(iterable)
returns the sum of a sequence of floating-point numbers, accurately computed.math.isnan(x)
returnsTrue
if the given numberx
is not a number (NaN) andFalse
otherwise.math.pow(x, y)
returns the value ofx
raised to the power ofy
.math.sqrt(x)
returns the square root of the given numberx
.
Random Numbers
- The
random
module in Python provides several functions and methods for generating random numbers and performing random operations on sequences. random.random()
returns a random float in the interval between 0.0 to 1.0.random.randrange(start, stop, step)
returns a random integer from the range specified bystart
,stop
, andstep
.random.randint(a, b)
returns a random integer betweena
andb
inclusive.random.choice(sequence)
returns a random item from the given sequence.random.shuffle(sequence)
shuffles the given sequence in place.
Modules
- A module is a file containing definitions and statements.
- Modules can be imported into a program to use their functions and variables.
- Specific functions can be imported from a module using the
from ... import ...
statement.
Recursion
- Recursion is a technique where a function calls itself as a subroutine.
- A recursive function can be used to calculate the factorial of a number.
Global and Local Variables
- Global variables can be used to store data that needs to be shared across multiple function calls.
- Local variables can be used to temporarily store data that is specific to a particular function call.
- The scope of variables should be considered when writing functions in Python.
Commonly Used Built-in Functions
min()
returns the minimum value in an iterable object (such as a list).max()
returns the maximum value in an iterable object (such as a list).sum()
returns the sum of the elements in an iterable object (such as a list).round()
returns a floating-point number to the specified number of decimal places.
Type Conversion Functions
int()
is used to convert a number or a string representation of a number to an integer.float()
is used to convert a number or a string representation of a number to a floating-point number.str()
is used to convert any data type to a string representation.bool()
is used to convert any data type to a Boolean value (True or False).
