Practical uses for infinite loops:
Analyzing a gene file in FASTA format. Each FASTA file is a different length and if you want a tool that can be used for different files, an infinite loop using readline and an if-statement of "if readline() = " ": break" will kill the program at the end of reading the file. this can be extended to spreadsheets/matrices as a quick and dirty ("inelegant", as my mentor would say) way to code.

half the course already and it was a really good idea to look at the whole basics of python again ^^

Hello i used this code to make a simple calculator but its giving me a syntax error highlighting the ' e ' . Please help


operator = input("Select your : ")

first_number = input("Enter first number: ")
second_number = input("Enter second number: ")

if operator == "addition":
print(float(first_number) + float(second_number))
elif operator == "subtraction":
print(float(first_number) - float(second_number))
elif operator == "multiplication":
print(float(first_number) * float(second_number))
elif operator == "division":
print(float(first_number) // float(second_number))
elif operator != "addition" or "subtraction" or "multiplication" or "division":
print("error")

Thank you, your videos are awesome, but you have 2 killer mistakes in your video, 1. You didn't do a zoom on the screen to be seen(lines of codes).
2. Your videos doesn't have like 480p resulotion, either you must select 1080p which needs very well Internet to load which sometimes impossible or 360p which can't be seen(lines of codes)
* That's why I can't follow your videos all the time due to my bad internet and your mistakes as well
