# Program 1
# Hello World!
# 1000+ Python Programs by

print("Hello World!")


Hello World!


This is the first program one tries when learning any new programming language. This is like a small test program to see that everything is good to get started.

⭐ We learnt the first function in Python 3.x called the print() function.

print() is a build in function in Python3

print(*objects, sep=' ', end='\n', file=None, flush=False)


Troubleshooting & most common errors:

Note: If you are using Python 2.x print is a statement and you will write the Hello World program like below,

print "Hello World!"

If you run the above program in Python3 you will get an error,

print 'Hello World!'
SyntaxError: Missing parentheses in call to 'print'. 
Did you mean print('Hello World!')?

Python3 also known as Python 3.0, Python 3000, or Py3K was released in the year 2008, which is not backward compatible with Python 2.x

If you miss the double or single quotes around "Hello World!" string.
# python3 
File "", line 1
print("Hello World!)
SyntaxError: EOL while scanning string literal

If you add spaces or tabs before the print function:
# python3 
File "", line 1
    print('Hello World!')
IndentationError: unexpected indent

If you miss the closing parenthesis:
# python3 
File "", line 2
SyntaxError: invalid syntax
