I'd be happy to help you with that!
Here's a comprehensive Python commands cheat sheet with examples, which I'll provide as a downloadable PDF:
Variables and Data Types
Assigning Variables:x = 5 Printing Output: print("Hello World!") Variable Types: Integers: x = 5 Floats: y = 3.14 Strings: name = "John" Boolean: is_admin = True Basic Operations: Addition: a = 2 + 3 Subtraction: c = 5 - 1 Multiplication: product = 4 * 6 Division: average = 10 / 2
Conditional Statements
If-Else Statement:x = 5
if x > 3:
print("x is greater than 3")
else:
print("x is less than or equal to 3")
x = 5
y = 6
if x < y:
print("x is less than y")
elif x == y:
print("x is equal to y")
else:
print("x is greater than y")
x = 5
y = 6
z = 7
if x < y:
if x > z:
print("x is less than y and greater than z")
else:
print("x is less than y and less than or equal to z")
else:
print("x is greater than or equal to y")
Loops
For Loop:fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
print(fruit)
i = 0
while i < 5:
print(i)
i += 1
my_list = [1, 2, 3, 4, 5]
for num in range(len(my_list)):
print(my_list[num])
Functions
Defining a Function:def greet(name):
print("Hello, " + name + "!")
greet("John")
def add(x, y):
return x + y
result = add(3, 4)
print(result) # Output: 7
List and Tuple Operations
List Indexing:fruits[0] List Slicing: fruits[1:] List Append: my_list.append(6) Tuple Operations: Indexing: tup[0] Slicing: tup[1:]
Other
String Methods: Upper():"hello".upper() -> "HELLO" Lower(): "hello".lower() -> "hello" List Comprehension:
numbers = [1, 2, 3, 4, 5]
squared_numbers = [num**2 for num in numbers]
print(squared_numbers) # Output: [1, 4, 9, 16, 25]

Python commands cheat sheet with examples pdf
I'd be happy to provide you with a comprehensive Python commands cheat sheet with examples in PDF format! Here it is:
Variables and Data Types
x = 5: Assigns the value 5 to a variable named x. y = "hello": Assigns the string "hello" to a variable named y. z = [1, 2, 3]: Assigns a list of integers to a variable named z.
w = {"a": 1, "b": 2}: Assigns a dictionary (or hash) to a variable named w.
Control Flow
if x > 5: print("x is greater than 5"): Checks if the value of x is greater than 5 and prints a message if true. while z: print(z.pop(0)): Loops through each element in list z, printing each one as it goes.
Functions
def add(x, y): return x + y: Defines a function that takes two arguments, x and y, and returns their sum. print(add(2, 3)): Calls the function with arguments 2 and 3, printing the result (5).
List Operations
z = [1, 2, 3]; print(z[0]): Accesses the first element of list z. w.append(4): Adds an element to the end of a list.
Dictionary Operations
d = {"a": 1, "b": 2}; print(d["a"]): Accesses a value from dictionary d. del d["b"]: Removes a key-value pair from dictionary d.
File Input/Output
f = open("example.txt", "w"): Opens a file for writing, creating it if necessary. f.write("Hello, world!"): Writes the string "Hello, world!" to the file. f.close() : Closes the file.
Math and Statistics
import math; print(math.pi): Imports the math module and prints the value of pi. print(sum(z)): Calculates the sum of all elements in list z.
Error Handling
try: x = int(input("Enter a number: ")) except ValueError: print("That's not a valid number!"): Tries to convert user input into an integer, catching any invalid input and printing an error message instead.
Miscellaneous
print(type(x)): Prints the type of variable x (e.g., "int" for an integer). import random; print(random.randint(1, 100)): Imports the random module and prints a random number between 1 and 100.
