# Example strings="SparkByExamples is Good Website."# Get substring using Slicingsubstring=s[0:5]print(substring)# Output:# Spark 3. Regular Expressions – Substring Match to Pattern A regular expression can be used for searching and extracting substrings from strings in Python. This allows yo...
s2= getSubstringBetweenTwoChars('J','g',s) print(s2) Output: ava2Blo In the above example, we found the position of characters J and g using the find() function and used the string-slicing technique to extract the string between these characters. String’s find() method returns in...

Replace(old,new) replaces the old occurrence of the substring old with the substring new. Find() reports the offset where the first occurrence of the substring occurs. >>> banner = “FreeFloat FTP Server” >>> print banner.upper() FREEFLOAT FTP SERVER >>> print banner.lower() freefloat...
def count(s, sub): result = 0 for i in range(len(s) + 1 - len(sub)): result += (s[i:i + len(sub)] == sub) return result The behavior is due to the matching of empty substring('') with slices of length 0 in the original string.Contributing...
