'while' is a keyword 'while True' is a complete while statement with a boolean value. The 'while' keyword needs to be followed by a condition that will return a boolean value. Syntax: 🔸 while condition: code In your question, True is already a boolean value so the code inside the while block will execute infinitely unless a break keyword is executed. EDIT: (for recent examples you've posted) From your first example: 🔹 while True means that it will print i and add 1 to it infinitely... 🔹 however, there is a condition if i >= 5 where if it becomes True, the break will execute then the while loop will stop. Second example: 🔹 Same output with the first one but different approach 🔹 In this case, the condition is in the while statement, and once i becomes greater or equal to 4, the while loop will stop. For better understanding, I adjusted the value of i so it will be the same for both examples. https://code.sololearn.com/cVp44Cs9v0OQ/?ref=app

while : syntax error while true : start of loop with true condition runs until innerly break Can you show your code snippets about what is your question actually about???

while True : #condition is always True, loop runs until breaked explicitly while i<=4 : # loop runs until i<=4 becomes false.

i = 0 while True: print(i) i = i + 1 if i >= 5: break i = 1 while i <=4: print(i) i = i + 1
