Answer:
I am writing a Python program that deletes players from the file whose names whose names do not begin with a vowel which means their names begin with a consonant instead. Since the SomePlayers.txt is not provided so i am creating this file. You can simply use this program on your own file.
fileobj= open('SomePlayers.txt', 'r')
player_names=[name.rstrip() for name in fileobj]
fileobj.close()
vowels = ('a', 'e', 'i', 'o', 'u','A','E','I','O','U')
player_names=[name for name in player_names
if name[0] in vowels]
fileobj.close()
print(player_names)
Explanation:
I will explain the program line by line.
First SomePlayers.txt is opened in r mode which is read mode using open() method. fileobj is the name of the file object created to access or manipulate the SomePlayers.txt file. Next a for loop is used to move through each string in the text file and rstrip() method is used to remove white spaces from the text file and stores the names in player_names. Next the file is closed using close() method. Next vowels holds the list of characters which are vowels including both the upper and lower case vowels.
player_names=[name for name in player_names
if name[0] in vowels]
This is the main line of the code. The for loop traverses through every name string in the text file SomePlayers.txt which was first stored in player_names when rstrip() method was used. Now the IF condition checks the first character of each name string. [0] is the index position of the first character of each players name. So the if condition checks if the first character of the name is a vowel or not. in keyword is used here to check if the vowel is included in the first character of every name in the file. This will separate all the names that begins with a vowel and stores in the list player_names. At the end the print statement print(player_names) displays all the names included in the player_names which begin with a vowel hence removing all those names do not begin with a vowel.
Drones are become more advanced than ever before. Are now, they are starting to impact recreation. They are small, light, and can maneuver incredibly fast. They are being used in movies, skits, short films, and even high-end videos. Here are some ways drones are changing entertainment:
- Providing high-quality filming, even from 200 feet in the air.
- Reaching spaces where bulky helicopters cannot fit into safely
- Laser shows, where drones shine lights and lasers.
Right now, if you tried to hold your phone still to capture a video, you would not be able to do it. Upon checking the footage, you would see the camera shaking, even if it's just tiny bit. While you can lean it on a surface to fix this, it simply cannot be done in the air to capture. Not to worry, though, you've got drones. They can shoot a steady shot 200 feet in the air. The only thing that could rival drones are expensive, bulky choppers. The drones are cheaper and are mass produced.
However, drones are not only being used to filming movies and films. They are also being used for a different kind of entertainment: Shows. Drones move in formation and shine lights in the night sky, like we saw in the Winter Olympics. They are truly stunning(pics attached).
