Python Cheatsheet: Essential Tips for Every Developer

AI generated image

Whether you’re a beginner or a 10X developer, having a quick Python cheatsheet can be a lifesaver. Python’s simplicity and readability make it ideal for many applications, from application development to data science. This guide covers key concepts, tips, and frequently-used snippets to make your coding process silky smooth.

01 — Basic Data Types

# Basic Data Types
x = 3 # Integer
y = 3.0 # Float
name = "Simone" # String
is_active = True # Boolean

02 — Type Conversion

• Use `int()`, `float()`, `str()`, `bool()` for conversions:

age = "25"
age_int = int(age) # Converts age to integer, resulting in 25
age_float = float(age) # Coverts age to float, resulting in 25.0
age_string = str(age_float) # Converts age_float to a string, resulting in "25.0"
age_has_value = bool(age) # Coverts age to boolean, resulting in True (since "25" is non-empty)

03 — Lists (Mutable Sequences)

Lists can store multiple values and allow modification.

fruits = ["apple", "banana", "cherry"]
fruits.append("orange")      # Adds "orange" to the list

04 — Tuples (Immutable Sequences)
