- Basic Structure of Conditional Statements
0 or null is false, the rest is true
if Decision Condition.
Block of statements... Can be multi-line

Block of statements... Can be multi-line
The code is as follows:
day=12
# Multi-conditional statement judgment
if day<7:
print('Activity challenge failed, try again!');
day+=6
elif day>=7 and day <14:
print('Prize 2 for 1, oversized mouse pad/customized fridge sticker');
elif day>=14 and day <21:
print('Prize 3 choices, oversized mouse pad/customized fridge sticker/year of the tiger notebook');
elif day>=21 and day <30:
print(' Prizes 5 choose 3, oversized mouse pad/customized fridge stickers/Year of the Tiger notebook/shoulder bag/WuKong bear dolls');
elif day>30:
print(' Prizes 5 choose 3, oversized mouse pad/customized fridge stickers/Year of the Tiger notebook/shoulder bag/WuKong bear dolls');The effect is as follows:
Two.while loop statement
As we all know, the program is generally in order to execute the code, in the code execution process, there will be complex statements, this time the loop statement will play a role
Execute the body of the loop while the condition holds; in python, there is no do while.
while Decision condition.
Block of statements... Can be multi-line
The code is as follows:
day=0
# while loop statements
while day<30:
day+=7
if day<7:
print('Activity challenge failed, try again!');
elif day>=7 and day <14:
print('Article updated for %s day in a row, prize 2 for 1, oversized mouse pad/customized fridge sticker' % (day));
elif day>=14 and day <21:
print('Article updated for the %sst day in a row, 3 prizes to choose from, oversized mouse pad/customized fridge sticker/year of the tiger notebook' % (day));
elif day>=21 and day <23:
print('Article continuously updated on the %s day, 5 prizes to choose 3, oversized mouse pad/customized fridge sticker/year of the tiger notebook/shoulder backpack/WuKong bear hand puppet' % (day));The result is as follows.
