Programming Tasks

1. Write a Python program that computes round(pow((3**4 + 5*6**7)/8, 0.5), 3) without importing any modules.

2. Using jieba, count the number of Chinese characters and words in a given sentence.

3. Draw a square of side 200 using the turtle library:

import turtle
d = 0
for i in range(4):
    turtle.fd(200)
    d = d + 90
    turtle.seth(d)

4. Count the occurrences of each university type in a list of 39 "985" universities.

File Handling Example

txt = open("book.txt", "r")
print(txt)
txt.close()

The output shows the file object representation, e.g.,

<_io.TextIOWrapper name='book.txt' mode='r' encoding='utf-8'>
