These are some basic python functions. Basic Python commands are fundamental building blocks for writing programs. Here are some of the most commonly used ones:
- Output: print(): Used to display output to the console.
Python
print("Hello, World!")
- Input: input(): Used to get user input from the console. The input is always read as a string.
Python
name = input("Enter your name: ") print("Hello, " + name + "!")
- Data Type Operations: type(): Returns the type of an object.
Python
x = 10 print(type(x)) # Output: <class 'int'>
len(): Returns the number of items in an object (e.g., string, list, tuple, dictionary).
Python
my_list = [1, 2, 3] print(len(my_list)) # Output: 3
int(), float(), str(), bool(): Used for type conversion.
Python num_str = "123" num_int = int(num_str)
- Control Flow: if, elif, else: Used for conditional execution.
Python
age = 20 if age >= 18: print("Adult") else: print("Minor")
for: Used for iterating over sequences (e.g., lists, strings, ranges).
Python
for i in range(5): print(i)
while: Used for looping as long as a condition is true.
Python
count = 0 while count < 3: print(count) count += 1
- List Operations: append(): Adds an element to the end of a list.
Python
my_list = [1, 2] my_list.append(3) # my_list is now [1, 2, 3]
insert(): Inserts an element at a specified position.
Python
my_list.insert(0, 0) # my_list is now [0, 1, 2, 3]
remove(): Removes the first occurrence of a specified value.
Python
my_list.remove(2) # my_list is now [0, 1, 3]
- Modules: import: Used to import modules and access their functionalities.
Python
import math print(math.sqrt(16))
# Output: 4.0
