⏱️ Python — time.sleep() Practice Assignments

1) Simple Sleep Print

Write a program that prints “Hello”, then waits 2 seconds, then prints “World”.

---

2) Three-Second Pause

Print “Start”, pause for 3 seconds using time.sleep(3), then print “End”.

---

3) Countdown from 5

Using a loop and sleep(1), print:

5
4
3
2
1

---

4) Timer Print

Print current time (seconds since epoch), sleep 2 seconds, then print it again.

---

5) Sleep in Loop

Loop 5 times printing index 0–4 with a 1-second delay between each.

---

6) Prompt + Wait

Ask the user for their name. Print “Checking…”, sleep 1 second, then print “Welcome, !”.

---

7) Sleep with Message

Write:

print("Sleeping…")
time.sleep(3)
print("Back!")

so output shows a pause.

---

8) Wait for User Input

Ask user:

Press Enter to continue…

After pressing Enter, sleep 2 seconds and then print “Done!”.

---

9) Two-Phase Timer

Print “Phase 1”, sleep 1 second; then “Phase 2”, sleep 2 seconds; then “Finished”.

---

10) Speed Test (Slow / Fast)

Loop 3 iterations:

• Sleep 1 second each

• Print time each iteration

---

11) Sleep with Conditional

Ask user whether to sleep (“yes/ no”). If “yes”, sleep 3 seconds; else print “Skipping sleep”.

---

12) Delay Before Exit

Print “Program will end in 3 seconds…” Sleep 3 seconds, then exit.

---

13) Alternating Messages

Use loop:

print("Tick")
sleep(0.5)
print("Tock")
sleep(0.5)

repeat 3 rounds.

---

14) Sleep Progress Bar

Use loop and sleep to show:

[=   ]
[==  ]
[=== ]
[====]

pause 1 second between each.

---

15) Sleep Before Function

Define a function delayed_print(msg, delay) that sleeps for delay seconds then prints msg.

---

16) Sleep With Milliseconds

Use time.sleep() with a fractional delay (e.g., 0.3 seconds) inside a loop of 10 prints.

---

17) Date/Time Stamp Before & After Sleep

Print:

Before: <datetime.now()>
sleep(2)
After: <datetime.now()>

---

18) Sleep in Recursion

Write a recursive function that prints a number and sleeps 1 second, recursing until 0.

---

19) Countdown with Message

Countdown from 5 to 1; when reaching 1, sleep 2 seconds then print “Go!”.

---

20) Sleep & Multiplication Table

Ask user for a number. Print its multiplication table with 1-second pause between lines.

---

🧠 What You’re Practicing

• how time.sleep() pauses execution

• adding delays in loops

• pausing between messages

• timing and user experience flow

---

📌 Example Starter

import time

print("Hello")
time.sleep(2)
print("World after 2 seconds")

or

import time

for i in range(5, 0, -1):
    print(i)
    time.sleep(1)
print("Blast off!")
