1. Fibonacci series

Fibonacci series, the first two items of the series are 1, and each item after is the sum of the first two items.

#!/usr/bin/env python3
a, b = 0, 1
while b < 100:
    print(b)
    a, b = b, a + b

print(a, end=' ')

2. Power series.

Write a program to calculate power series: e ^ x = 1 + X + x ^ 2 / 2! + x ^ 3 / 3! +... + x ^ n / N! (0 < x < 1).

#!/usr/bin/python3
x = float(input("Enter the value of x:"))

n = term = 1
result = 1.0
while n <= 100:
    term *= x/n
    result += term
    n += 1
    if term < 0.0001:
        break
print("No of Times={} and Sum = {}".format(n, result))

3. Multiplication table

Print multiplication tables up to 10.

#!/usr/bin/env python3
i = 1
print('-' * 60)
while i < 11
    n = 1
    while n <= 10:
        print("{:d}*{:d}={:d}".format(n, i, i * n), end=" ")
        n += 1
    print()
    i += 1
print('-' * 60)

• print('-' * 60): a string repeated 60 times for output

4. Print asterisk

Print asterisks of various shapes

• Up right triangle

#!/usr/bin/env python3
n = int(input('Enter the number of rows:'))
i = 1
while i <= n:
    print('*' * i)
    i += 1

• Right triangle down

#!/usr/bin/env python3
n = int(input('Enter the number of rows:'))
i = n
while i > 0:
    x = '*' * i
    y = " " * (n - i)
    print(y + x)
    i -= 1

• diamond

#!/usr/bin/env python3
n = int(input('Enter the number of rows:'))
i = 1
while i < n:
    x = '*' * (2 * i - 1)
    y = " " * (n - i)
    print(y + x)
    i += 1
while i > 0:
    x = " " * (n - i)
    y = '*' * (2 * i - 1)
    print(x + y)
    i -= 1

5. Stick game

There are 21 sticks. The user selects 1-4 sticks, and then the computer selects 1-4 sticks. Whoever chooses the last stick will lose. (the total number of sticks selected by users and computers in one round can only be 5)

#!/usr/bin/env python3
sticks = 21

while True:
    print("Sticks left: ", sticks)
    sticks_token = int(input("Take sticks(1-4):"))
    if sticks == 1:
        print("Failed!")
        break
    if sticks_token >= 5 or sticks_token <= 0:
        print("Choose wrong number! continue:")
        continue
    print("computer took:", 5-sticks_token, "\n")
    sticks -= 5

Note: there is no doubt that you will lose. Ha ha!
