count(): Count the occurrences of a substring in the string\nsubstring_count = sample_string.count(\"l\")\nprint(f\"Count of 'l' in the string: {substring_count}\")\n\n# 6. replace(): Replace a substring with another substring\nreplaced_string = sample_string.replace(\"Hello\", \"Hi\")\nprint(f\"String after replacement: {replaced_string}\")\n\n# 7. split(): Split the string into a list of substrings based on a delimiter\nsplit_string = sample_string.split(\",\")\nprint(f\"String after split: {split_string}\")\n\n# 8. strip(): Remove leading and trailing whitespaces from the
