I don’t believe that you can reverse that. Instead, do QP = point * hours That way, you instantiate the new variable, and set it to the product of the points and the hours. Some other issues: your point variable isn’t defined either. You need self.point = point in order to have the variable as … Read more
You could use Exrex. Install with pip install exrex. Then execute in terminal: exrex ‘Good (Morning|afternoon|evening) my (friends|family|brothers|sisters)\. hope you like (apple|orange|grape) juice\.’ Make sure not to forget the backslashes \ before the dots ., as dots are a special character inside regexes. This will return: Good Morning my friends. hope you like apple juice. … Read more
To apply the logic of “not any” you would want to check if it is any of the valid results then invert. (NOR) if not (diff == “1” or diff == “2” or diff == “3”): Or applying DeMorgan’s theorem this would be equivelent to “not equal to 1 AND not equal to 2 AND … Read more
Add printTwice(‘bruce’) on a new line after the function, with no indentation like so: def printTwice(bruce): print(‘bruce’) print(‘bruce’) printTwice(‘bruce’) This line will call your printTwice function, passing the value ‘bruce’ to the variable bruce, which is not used. 1 solved User-Defined Functions and Learning to Think Like a Computer Scientist with Python [closed]
There are many ways, but this seems to be the shortest path: Answer2 = “Yes” while Answer2 == “Yes”: … Answer2 = input(“Do you want to restart? (Yes/No): “) Typically you might want to .lower ().strip () Answer2 too. 4 solved Restarting code in Python 3.1 [closed]

Hmm, you could use the character class \S+ to designate a word. \S is equivalent to [^\s] which is itself equivalent to [^ \v\t\f\n\r] (in order I typed them: white space, vertical tab, horizontal tab, form feed, newline, carriage return). [^ … ] indicates a negated class, where all characters will be matched, except those … Read more
Python’s comparison operators wisely refuse to work for variables of incompatible types. Decide on the criterion for sorting your list, encapsulate it in a function and pass it as the key option to sort(). For example, to sort by the repr of each element (a string): l.sort(key=repr) To sort by type first, then by the … Read more

I suspect that’s what you’re looking for: def hourglassSum(): arr = [] for i in range(0,6): arr1=map(int,input().split()) arr.append(list(arr1)) sum=[] for i in range(len(arr)-2): for j in range(min(len(arr[i]), len(arr[i+1]), len(arr[i+2]))-2): sum.append(arr[i][j]+arr[i][j+1]+arr[i][j+2]+arr[i+1][j]+arr[i+2][j]+arr[i+2][j+1]+arr[i+2][j+2]) maxi=max(sum) print(maxi) Two notes: (1) you want to persist each iteration of the first loop, what you were doing was just overwriting your variable with … Read more
You can use the string module, with string.ascii_uppercase and string.ascii_lowercase. If you type: import string string.ascii_uppercase You get: ‘ABCDEFGHIJKLMNOPQRSTUVWXYZ’ If you type: string.ascii_lowercase You’ll get the same result, but in lowercase. To solve your problem you can do: import string upper_case = list(string.ascii_uppercase) lower_case = list(string.ascii_lowercase) upper_case and lower_case will be both lists ranging from … Read more

So there are several red flags right away… (multiple mainloop calls, classes in classes, calling root inside listbox) It seems like you are missing one of the main concepts of many gui frameworks, and that is that 1 window is not 1 application.

The way you wrote it, the script will end after the first error. If you’d like to check for a string, display a message and still ask for input, you could try something like this: i = 0 total = 0 while i < 10: try: a = int(input(f’Enter a number (position {i}): ‘)) total … Read more
