I'm new to python and decided to practice by building a game similar to snake with the turtle library. I was able to initiate the turtle to continually move forward with a while True loop, but now I'm having trouble with getting the turtle to break this loop to make turns. I have tried various different ways of writing my conditionals but I can't seem to figure out where the issue is. Thanks in advance!
import turtle
window = turtle.Screen()
snake = turtle.Turtle()
snake.speed(1)
snake.penup()
#Functions that move the snake:
def forward():
while True:
snake.forward(.7)
def left():
snake.left(90)
def right():
snake.right(90)
#Movement functions all put together:
def movesnake():
while True:
entry = input()
if entry == 'w':
forward()
if entry == 'a':
left()
if entry == 'd':
right()
movesnake()

Try this approach to move:
def forward():
turtle.forward(how-many-pixels-forward)
turtle.onkey(forward,'what-key-you-want-to-listen-to') #when key pressed call forward function

The turtle module provides turtle graphics primitives, in both object-oriented and procedure-oriented ways. Because it uses Tkinter for the underlying graphics, it needs a version of Python installed with Tk support.
turtle.onkey() This function is used to bind fun to the key-release event of the key. In order to be able to register key-events, TurtleScreen must have focus.

You can try increasing the value of the forward function:
def forward():
while True:
snake.forward(5)
