## 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.
#### More Information
Time module documentation on the sleep function.
Another method to achieve a time delay will be by using selenium related waits, which can be either implicit wait or waiting until an expected condition.
Implicit Wait
```
from selenium import webdriver
#below code initializes a chrome webdriver, and we can apply waits using it
driver = webdriver.Chrome('driver_path')
driver.implicitly_wait(5)
```
Wait until Excpected Condition
```
self.wait.until(EC.presence_of_element_located((By.ID, ''))
```
