with strings

Strings are so popular that even turtle graphics in Python have

functions for taking strings as input and writing them to the

screen. The function to ask a user for a string, or text, in the

Turtle library is turtle.textinput(); this opens a pop-up window

asking the user for text input and lets us

store that as a string value. Figure 3-7 shows

the nice graphical window that Turtle pops

up for us when we use turtle.textinput("Enter

your name", "What is your name?"). There are

two arguments in Turtle’s textinput() func-

tion. The first argument, "Enter your name", is

the window title for the pop-up window. The

second argument, "What is your name?", is the

prompt that asks the user for the information

we want.

The function for writing a string on the turtle screen is write();

it draws text in the turtle’s pen color and at the turtle’s location on

the screen. We can use write() and turtle.textinput() to combine
