## Sleep How Can I Make a Time Delay in Python
|
|
|
|
The `time` module in the Python standard library contains the function `sleep()` which suspends a program for a given number of seconds.
|
|
|
|
Example:
|
|
|
|
```
|
|
import time
|
|
|
|
for letter in 'hello, world!':
|
|
print(letter)
|
|
time.sleep(2) # sleep 2 seconds between each print
|
|
```
|
|
|
|
When using sleep, you can define the amount of time that the program is suspended using either an integer (a whole number) or a float (a number with decimal places), depending on the level of control you want over the time that the program sleeps. For example, `time.sleep(10)` would suspend a program for 10 seconds, while `time.sleep(5.5)` would suspend a program for five and a half seconds.
