Python regex to find sequences of one uppercase letter followed by lowercase letters

| |

Examples :

  Input:  Geeks  Output:  Yes  Input:  pythonengineering  Output:  No 

Approach: using re.search ()

To check if a sequence of one uppercase letter followed by lowercase letters, we use the regular expression “ [AZ] + [az] + $ ".

# Python3 code to search for single top sequences
# case of letters followed by lowercase letters

import re

 
# Function to match a string

def match (text):

 

# regular expression

pattern = ’[ AZ] + [az] + $ ’

  

  # search pattern

if re.search (pattern, text):

return ( ’Yes’ )

else :

r eturn ( ’No’ )

 
# Driver function

print (match ( "Geeks" ))

print (match ( "geeksforGeeks" ))

print (match ( "geeks" ))
