Can a single python statement be written over multiple lines?
Python statements are the code instructions that are executed by the Python interpreter. Python executes statements one by one as they appear in the code. Let’s look at some simple statement examples. Python Multi-line StatementsPython statements are usually written in a single line. The newline character marks the end of the statement. If the statement is very long, we can explicitly divide it into multiple lines with the line continuation character (\). Let’s look at some examples of multi-line statements. message = "Hello There.\nYou have come to the right place to learn Python Programming.\n" \ "Follow the tutorials to become expert in Python. " \ "Don't forget to share it with your friends too." math_result = 1 + 2 + 3 + 4 + \ 5 + 6 + 7 + 8 + \ 9 + 10 print(message) print(math_result)Python Statements Python supports multi-line continuation inside parentheses ( ), brackets [ ], and braces { }. The brackets are used by List and the braces are used by dictionary objects. We can use parentheses for expressions, tuples, and strings. message = ("Hello\n" "Hi\n" "Namaste") math_result = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 + 10) prime_numbers_tuple = (2, 3, 5, 7, 11, 13, 17) list_fruits = ["Apple", "Banana", "Orange", "Mango"] dict_countries = {"USA": "United States of America", "IN": "India", "UK": "United Kingdom", "FR": "France"} Can we have multiple statements in a single line?We can use a semicolon (;) to have multiple statements in a single line. Python Simple StatementsPython simple statement is comprised of a single line. The multiline statements created above are also simple statements because they can be written in a single line. Let’s look at some important types of simple statements in Python. 1. Python Expression Statementi = int("10") # expression is evaluated and the result is assigned to the variable. sum = 1 + 2 + 3 # statement contains an expression to be evaluated first. 2. Python Assignment Statementcount = 10 # value is assigned to the variable, no expression is evaluated message = "Hi" 3. Python Assert Statementassert 5 < 10 assert (True or False) Read more at Python assertions. 4. Python pass Statementdef foo(): pass # pass statement Read more at pass statement in Python. 5. Python del Statementname = "Python" del name # del statement 6. Python return Statementdef foo(): return 10 # return statement Recommended Read: return statement in Python. 7. Python yield Statementdef yield_statement(): yield 'Statement 1' # yield statement Read more at yield in Python. 8. Python raise Statementdef raise_example(): raise TypeError('Exception Example') # raise statement Read more about exception handling in Python. 9. Python break Statementnumbers = [1, 2, 3] for num in numbers: if num > 2: break # break statement Read more at Python break statement. 10. Python continue Statementnumbers = [1, 2, 3] for num in numbers: if num > 2: continue # continue statement print(num) Further Reading: Python continue statement 11. Python import Statementimport collections import calendar as cal from csv import DictReader Recommended Read: import in Python. 12. Python global Statementname = "Python" def global_example(): global name # global statement name = "Flask" print(name) # prints Python global_example() print(name) # prints Flask 13. Python nonlocal Statementdef outer_function(): scope = "local" def inner_function(): nonlocal scope # nonlocal statement scope = "nonlocal" print(scope) inner_function() print(scope) outer_function() Python Compound StatementsPython compound statements contain a group of other statements and affect their execution. The compound statement generally spans multiple lines. Let’s briefly look into a few compound statements. 1. Python if Statementif 5 < 10: print("This will always print") else: print("Unreachable Code") Recommended Read: Python if-else statement 2. Python for Statementfor n in (1, 2, 3): print(n) Further Reading: Python for loop 3. Python while Statementcount = 5 while count > 0: print(count) count -= 1 Read more at Python while loop. 4. Python try Statementtry: print("try") except ValueError as ve: print(ve) 5. Python with Statementwith open('data.csv') as file: file.read() 6. Python Function Definition StatementA python function definition is an executable statement. Its execution binds the function name in the current local namespace to a function object. The function is executed only when it’s called. 7. Python Class Definition StatementIt’s an executable statement. Python class definition defines the class object. 8. Python Coroutines Function Definition Statementimport asyncio async def ping(url): print(f'Ping Started for {url}') await asyncio.sleep(1) print(f'Ping Finished for {url}') SummaryPython statements are used by the Python interpreter to run the code. It’s good to know about the different types of statements in Python. References:
How do you write a Python statement that can expand over multiple lines?In Python, the statements are usually written in a single line and the last character of these lines is newline. To extend the statement to one or more lines we can use braces {}, parentheses (), square [], semi-colon “;”, and continuation character slash “\”.
Can multiple Python statements be written on a single line?Practical Data Science using Python
These statements can very well be written in one line by putting semicolon in between. However, this practice is not allowed if there is a nested block of statements.
How do you write a single line and multiple lined comment in Python?Let's have a look at them!. Using multiple single # line comments. You can use # in Python to comment a single line: # THIS IS A SINGLE LINE COMMENT. ... . Using triple-quoted string literals. Another way to add multiline comments is to use triple-quoted, multi-line strings.. What is multiline statement in Python?Statements in Python typically end with a new line. Python does, however, allow the use of the line continuation character (\) to denote that the line should continue. For example − total = item_one + \ item_two + \ item_three.
