while
==============================
Examples in Python 3


```python
"""
Loop until x is certain value
"""
x = 0
while x < 10:
	x += 3
	print(x)


"""
Loop until x is certain value with while True and break
"""
x = 0
while True:
	x += 3
	print(x)
	if x > 10:
		break


"""
More useful while with break (nothing to iterate over) - take input until input is "done"
"""
my_str = ""
while True:
	inp = input("> ")
	if inp == "done":
		break
	my_str += inp
print(my_str)



```
