Accept if it fulfils the following conditions

 String length 9  3 small alphabet (3 lowercase letter)  3 number (3 digit)  3 big alphabet (3 uppercase letters)  1 st alphabet should be capital  Last alphabet should be a number  Two consecutive alphabets can’t be small

Reject if any of the condition is absent

Answer 1

*Please follow the comments to better understand the code.

**Please look at the Screenshot below and use this code to copy-paste.

***The code in the below screenshot is neatly indented for better understanding.

def check(s):
  
#Conditions applied 1,5,6
if len(s)==9 and s[0].isupper() and s[-1].isdigit():
upper_count = sum(1 for c in s if c.isupper())
lower_count = sum(1 for c in s if c.islower())
number_count = sum(1 for c in s if c.isdigit())
  
#Conditions 2,3,4
if upper_count==3 and lower_count==3 and number_count==3:
  
#Condition 7 { Two consecutive alphabets can’t be small }
for i in range(1,len(s)):
if s[i-1].islower() and s[i].islower() :
return 'reject'
else:
return 'reject'
#All conditions satisfies here, so accept
return 'accept'
  
else:
return 'reject'
  
  
### TEST CASES ###
print(check('ABiG1h2f3')) #ALL correct

# BELOW ALL SHOULD BE REJECTED
print(check('AbiG1h2f3')) # bi consecutive two small letters

print(check('aBiG1h2f3')) # Starts with small letter

print(check('ABiG1h2fe')) # doesn't end with number

print(check('ABiG1h')) #Length is not 9

print(check('ABiG1h334')) # has 4 numbers. Also only 2 small letters
