Python stands out as an exceptional computing language suitable for diverse applications such as backend development, mobile apps, and even game development! What sets Python apart is its code, which is not only easy to read but also easy to understand, opening up endless possibilities for creating unique solutions. One of Python's standout features is its extensive library of built-in functions, which simplifies even the most intricate tasks. This ease of use and the ability to handle complexity make Python a favorite among developers, providing a robust foundation for innovation and creativity.
List of Some Built-in Functions:
sum()
# Returns the sum of all items in seq
list = [1, 4, 6, 7, 7]
sum(list)
print(list)
# Output: 25
abs()
# returns the absolute value of a number
x = -5
absolute_value = abs(x)
print(absolute_value)
# Output: 5
len()
# Returns the length of an object
list = [4, 6, 3]
len(list)
print(list)
# Output: 3
max() & min()
# Finds the Highest Value
highest_val = [3, 6, 2, 10, 3, 7]
max(highest_val)
print(highest_val)
# Output: 10
########################################################
# Finds the Lowest Value
lowest_val = [3, 6, 2, 10, 3, 7]
min(lowest_val)
print(lowest_val)
# Output: 2
print()
# Prints the output in the console
print('hello world!')
# Output: hello world!
round()
# Rounds a floating point number to the nearest integer
rounded_number = round(3.14159)
print(rounded_numbers)
# Output: 2
range()
# Generates a sequence of numbers within a specified range,
# not including the end value
numbers = list(range(1, 5))
print(numbers)
# Output: [1, 2, 3, 4]
sorted()
# Returns a new sorted list from the elements of an iterable
sorted_list = sorted([3, 1, 4, 1, 5, 9, 2])
print(sorted_list)
# Output: [1, 1, 2, 3, 4, 5, 9]
enumerate()
# Returns pairs of index and value for each element in an iterable
for index, value in enumerate(['a', 'b', 'c']):
print(f"Index: {index}, Value: {value}")
## Output:
# Index: 0, Value: a
# Index: 1, Value: b
# Index: 2, Value: c
zip()
# Combines multiple iterables into tuples
zipped = zip([1, 2, 3], ['a', 'b', 'c'])
result = list(zipped)
print(result)
## Output: [(1, 'a'), (2, 'b'), (3, 'c')]
str() & int() & float()
# str() converts an integer to a string
number_str = str(5)
# Output: '5'
# int() converts a string to an integer
string_int = int('3')
# Output: 3
# float() converts an integer to a floating point number
integer_float = float(5)
# Output: 5.0
any() & all()
# any() is used to check if at least one element in the
# numbers list is greater than 5.
# Using any()
numbers = [2, 4, 0, 7, 9]
# Check if at least one element is greater than 5
result_any = any(num > 5 for num in numbers)
print(f"Any element greater than 5? {result_any}")
# Output: True (because 7 and 9 are greater than 5)
#######################################################
# all() is used to check if all elements in the grades list
# are greater than or equal to 70.
# Using all()
grades = [85, 92, 78, 90]
# Check if all grades are greater than or equal to 70
result_all = all(grade >= 70 for grade in grades)
print(f"All grades greater than or equal to 70? {result_all}")
# Output: True (because all grades are 70 or greater)
type()
# Using type() for different types of variables
# String
text = "Hello, Python!"
type_text = type(text)
print(type_text)
# Output: <class 'str'>
# Integer
number = 42
type_number = type(number)
print(type_number)
# Output: <class 'int'>
# Float
decimal = 3.14
type_decimal = type(decimal)
print(type_decimal)
# Output: <class 'float'>
# List
my_list = [1, 2, 3]
type_list = type(my_list)
print(type_list)
# Output: <class 'list'>
# Dictionary
my_dict = {'a': 1, 'b': 2}
type_dict = type(my_dict)
print(type_dict)
# Output: <class 'dict'>
In conclusion, Python's built-in functions play a pivotal role in enhancing the language's utility and efficiency. These functions serve as powerful tools, simplifying a wide array of tasks and allowing developers to accomplish complex operations with ease. The extensive library of built-in functions not only facilitates coding but also contributes to Python's appeal and versatility across various domains. From handling basic data types to supporting advanced operations, Python's built-in functions provide a solid foundation for developers, enabling them to focus on problem-solving and innovation.
