Python:

pants = "I am wearing pants."
# Method 1: Check if the string contains the word "pants"
if "pants" in pants:
print("I am wearing pants.")
else:
print("I am not wearing pants.")
# Method 2: Replace the word "pants" with "trousers"
pants = pants.replace("pants", "trousers")
print(pants)
# Method 3: Split the string into a list of words and check if "pants" is present
word_list = pants.split()
if "pants" in word_list:
print("Pants found in the string.")

JavaScript:

var pants = "I am wearing pants.";
// Method 1: Check if the string contains the word "pants"
if (pants.includes("pants")) {
console.log("I am wearing pants.");
} else {
console.log("I am not wearing pants.");
}
// Method 2: Replace the word "pants" with "trousers"
pants = pants.replace("pants", "trousers");
console.log(pants);
// Method 3: Split the string into an array of words and check if "pants" is present
var wordArray = pants.split(" ");
if (wordArray.includes("pants")) {
console.log("Pants found in the string.");
