Control flow is an order in which individual statements, instructions, or function calls are executed or evaluated. Python provides several control flows, such as conditional expressions, loops, or functional calls. These allow us to manage the execution path of your programs based on conditions or loops.
We'll concentrate on loops (for and while) and conditional statements (if statements) in this section.
Here are some of the main control flows which are used in Python programs:
It allows your Python program to use a certain code of blocks according to the given conditions.
Let's understand the conditional statement with a basic example:
temperature = 30
if temperature > 30:
print("Today is hot.")
elif temperature > 20:
print("today is warm.")
elif temperature > 10:
print("Today is cool.")
else:
print("It is a cold day.")
Output
It is used to execute the block of code repeatedly.
Let’s understand both loops with their syntax:
for variable in sequence:
# Code block executed for each item in the sequence
while condition:
# Code block executed as long as the condition is True
Example
Let’s create an example to demonstrate the use of for and while loops:
# for loop
print("For loop's output")
for i in range(5):
print(i)
# while loop
count = 0
print("While loop's output")
while count < 5:
print(count)
count += 1
Output
It is used to control the behavior of loops and conditional statements.
Let’s understand the control flow modifiers by their syntax:
# Break statement
while True:
# Some code
if some_condition:
break
# Continue Statement
for i in range(10):
if i % 2 == 0:
# Skip the rest of the loop for even numbers
continue
print(i)
# Pass statement
if condition:
pass # Placeholder for future code
It is used to handle the errors in Python programs using the try-and-catch block.
Try:
# Code may cause an exception except
ExceptionType:
# Code runs if an exception occurs
Try:
# Code may cause an exception except
ExceptionType:
# Code runs if an exception occurs
Understanding these control flows helps you write efficient and effective Python code based on the conditions and looping.

Python is commonly used for developing websites and software, task automation, data analysis, and data visualisation. Since it's relatively easy to learn, Python has been adopted by many non-programmers, such as accountants and scientists, for a variety of everyday tasks, like organising finances.
Learning Curve: Python is generally considered easier to learn for beginners due to its simplicity, while Java is more complex but provides a deeper understanding of how programming works.
The point is that Java is more complicated to learn than Python. It doesn't matter the order. You will have to do some things in Java that you don't in Python. The general programming skills you learn from using either language will transfer to another.
Read on for tips on how to maximize your learning. In general, it takes around two to six months to learn the fundamentals of Python. But you can learn enough to write your first short program in a matter of minutes. Developing mastery of Python's vast array of libraries can take months or years.
