Given a String, check if each segment is delimited by  K.

Input : test_str = ’72!45!geeks!best’, K = ‘!’ 

Output : True 

Explanation : All numerics and alphabets separated by delim border. 

Input : test_str = ’72!45geeks!best’, K = ‘!’ 

Output : False 

Explanation : No separation between 45 and geeks.

Method : Using isdigit() + isalpha() + loop

This is way in which this task can be performed. In this, we perform task of checking for alphabets and digits segments using isalpha() and isdigit(). Presence of any element, not entirely number or alphabet, is termed to non-delimited by K, and it remains unresolved during split().


# Python3 code to demonstrate working of
# Check if Elements delimited by K
# Using isdigit() + isalpha() + loop
# initializing string
test_str = '72@45@geeks@best'
# printing original string
print("The original string is : " + str(test_str))
# initializing splt_chr
K = "@"
res = True
# splitting elements
temp = test_str.split(K)
for ele in temp:
    # checking for non-alpha or non-digit
    if len(ele) > 1 and not ele.isdigit() and not ele.isalpha():
        res = False
# printing result
print("Are all delimited by K : " + str(res))


The original string is : 72@45@geeks@best
Are all delimited by K : True

Time Complexity: O(n)

Auxiliary Space: O(n)
