Python: Check if a given string contains two similar consecutive letters
Python Basic - 1: Exercise-124 with Solution
Write a Python program to check if a given string contains two similar consecutive letters.
Sample Solution-1:
Python Code:
def test(str1):
return any(c1 == c2 for c1, c2 in zip(str1, str1[1:]))
str = "PHP"
print("Original string: ",str)
print("Check for consecutive similar letters! ",test(str))
str = "PHHP"
print("\nOriginal string: ",str)
print("Check for consecutive similar letters! ",test(str))
str = "PHPP"
print("\nOriginal string: ",str)
print("Check for consecutive similar letters! ",test(str))
Sample Output:
Original string: PHP Check for consecutive similar letters! False Original string: PHHP Check for consecutive similar letters! True Original string: PHPP Check for consecutive similar letters! True
Flowchart:

Sample Solution-2:
Python Code:
def test(str1):
for el in str1:
if el*2 in str1:
return True
return False
str = "PHP"
print("Original string: ",str)
print("Check for consecutive similar letters! ",test(str))
str = "PHHP"
print("\nOriginal string: ",str)
print("Check for consecutive similar letters! ",test(str))
str = "PHPP"
print("\nOriginal string: ",str)
print("Check for consecutive similar letters! ",test(str))
Sample Output:
Original string: PHP Check for consecutive similar letters! False Original string: PHHP Check for consecutive similar letters! True Original string: PHPP Check for consecutive similar letters! True
