Some simple exercises and Python exercises for new python beginners

Preface

This article mainly shares some simple Python exercises, which is a good exercise for beginners who are learning python. I will not talk about them much below. Let's take a look at the detailed introduction.

Question 1: Use a while loop to input 1 2 3 4 5 6 8 9 10

a = 0while a < 10: a +=1  if a == 7:  continue print(a)

Question 2: Calculate the sum of all numbers from 1

Method 1:

a = 0b = 1while b <= 100: a = a + b b += 1print(a)

Method 2:

a = 0for i in range(101):  a = a + i  print(a)

Question 3: output all odd numbers in 1-100

a = 0while a <= 100: a += 1 if(a%2) == 0:  print(a)

Question 4: output all even numbers in 1-100

Method 1:

a = 0while a <= 100:  a += 1  if(a%2) == 0:    print(a-2+1)

Method 2:

a = 0while a <= 99:  a += 1  if(a%2) != 0:    print(a)

Question 5: Calculate the sum of all numbers of 1-2 + 3-4 + 5... 99

a = 0b = 0while a < 99:  a += 1  if a%2 == 1:   b += a  else:   b -= aprint(b)

Question 6: User Login (three chances to retry)

A = 0 while a <3: name = input ("Enter the User name:") password = input ("enter the password :") a + = 1 if name = 'wxd 'and password = '000000': print ("Login successful") exit () else: print ("input error, enter ") print (" three input errors, exit ") again ")
