1. Enter 123456 8910 using the while loop

2. Find all sums from 1 to 100.

3. Output all odd numbers from 1-100

4. Output all even numbers from 1-100

5. Find 1-2+3-4+5... The sum of all the numbers of 99

6. User login (three tries)

Programming ideas:

3. Write a code that outputs 1-100 first, add conditions in the middle, and skip until 100 when odd numbers are encountered.

Basic data types:

integer, int

# n1 = 123

# n2 = 456

# print(n1+n2)

# print(n1.__ add__(n2))

Gets the shortest representable binary number

n = 4

zq = n.bit_length()

print(zq)
