Python is one of the most popular programming languages, known for its simplicity and readability. If you’re learning Python, understanding loops and conditionals is crucial. These concepts form the backbone of decision-making and repetitive execution in Python programs. If you find recipes in hindi then visit Hubrecipes.
1. Python Conditionals (If-Else Statements)
Conditionals allow programs to make decisions based on conditions.
Basic If Statement
x = 10
if x > 5:
print("x is greater than 5")
If-Else Statement
x = 3
if x > 5:
print("x is greater than 5")
else:
print("x is not greater than 5")
If-Elif-Else Statement
x = 5
if x > 5:
print("x is greater than 5")
elif x == 5:
print("x is equal to 5")
else:
print("x is less than 5")
2. Python Loops
Loops help execute a block of code multiple times.
For Loop
for i in range(5):
print(i) # Prints numbers from 0 to 4
While Loop
x = 0
while x < 5:
print(x)
x += 1
3. Loop Control Statements
Python provides several loop control statements:
Break Statement
for i in range(5):
if i == 3:
break # Stops the loop when i is 3
print(i)
Continue Statement
for i in range(5):
if i == 3:
continue # Skips iteration when i is 3
print(i)
Pass Statement
for i in range(5):
if i == 3:
pass # Does nothing, acts as a placeholder
print(i)
4. Nested Loops and Conditionals
Python allows nesting loops and conditionals.
for i in range(3):
for j in range(3):
if i == j:
print(f"i and j are equal: {i}")
Conclusion
Understanding loops and conditionals is essential for writing efficient Python programs. Mastering these concepts will improve your ability to write logical and structured code.
