     Based on your indentation, you cannot start elif without if, you should always start if and then elif. you can check for condition as below:

     print("Enter number")N = int(input())if(N%2!=0): print("Weird")elif (N%2==0) and (N>=2 and N<=5): print("Not Weird")elif(N%2==0) and (N>=6 and N<=20): print("Weird")else: print("Not Weird")

     For your coding conventions, you can always look on to PEP 8 -- Style Guide for Python Code

     It's because you have missing values in your "nn" variable and seaborn distplot does not handle missing values, you can remove the missing values when plotting:

     df = pd.DataFrame([1,1,2,3,4,5,6,6,6,6,np.nan], columns = ["nn"])sns.distplot(df['nn'].dropna())-

     This will give you the plot:

   • Define exception error in python NameError

     Top Answer

     Answered Sep 03, 2021 · 2 votes

     If the intent is for e to be the exception, you need to assign it to that name as part of the except:

     def fixPdf(pdfFile): try: fileOpen = file(pdfFile, "a") fileOpen.write("%%EOF") fileOpen.close() print("Fixed") except Exception as e: print(f"Unable to open file: {pdfFile} with error: {e}") if __name__ == '__main__': fixPdf('Sample.pdf')

     You also need to print the messages if you want them to be visible, since the caller does not print the return value of the function.

     Your error was:

     NameError: name 'text' is not defined.

     Check your 10 number line code. You use buttons[text] but here text wasn't defined previously. That's why you got this error.

     Just change buttons[text] to buttons["text"] and put all text into "text". It will solve your problem.

     Editted code:

     from tkinter import *import tkinter.messageboxtk=Tk()tk.title("Tic Tac Toe")click=Truedef checker(buttons): global click if buttons["text"]==" " and click==True: buttons["text"]="X" click=False elif buttons["text"]==" " and click==False: buttons["text"]="O" click=True elif(button1["text"]=="X" and button2["text"]=="X" and button3["text"]=="X" or button4["text"]=="X" and button5["text"]=="X" and button6["text"]=="X" or button7["text"]=="X" and button8["text"]=="X" and button9["text"]=="X" or button1["text"]=="X" and button5["text"]=="X" and button9["text"]=="X" or button3["text"]=="X" and button5["text"]=="X" and button7["text"]=="X" or button1["text"]=="X" and button4["text"]=="X" and button7["text"]=="X" or button2["text"]=="X" and button5["text"]=="X" and button8["text"]=="X" or button3["text"]=="X" and button6["text"]=="X" and button9["text"]=="X"): tkinter.messagebox.showinfo("Winner X:You won the game") elif(button1["text"]=="O" and button2["text"]=="O" and button3["text"]=="O" or button4["text"]=="O" and button5["text"]=="O" and button6["text"]=="O" or button7["text"]=="O" and button8["text"]=="O" and button9["text"]=="O" or button1["text"]=="O" and button5["text"]=="O" and button9["text"]=="O" or button3["text"]=="O" and button5["text"]=="O" and button7["text"]=="O" or button1["text"]=="O" and button4["text"]=="O" and button7["text"]=="O" or button2["text"]=="O" and button5["text"]=="O" and button8["text"]=="O" or button3["text"]=="O" and button6["text"]=="O" and button9["text"]=="O"): tkinter.messagebox.showinfo("Winner O:You won the game")buttons=StringVar()button1=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button1))button1.grid(row=0,column=0,sticky=S+N+E+W)button2=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button2))button2.grid(row=0,column=1,sticky=S+N+E+W)button3=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button3))button3.grid(row=0,column=2,sticky=S+N+E+W)button4=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button4))button4.grid(row=1,column=0,sticky=S+N+E+W)button5=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button5))button5.grid(row=1,column=1,sticky=S+N+E+W)button6=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button6))button6.grid(row=1,column=2,sticky=S+N+E+W)button7=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button7))button7.grid(row=2,column=0,sticky=S+N+E+W)button8=Button(tk,text=" ",font=('Times 26 bold'),height=4,width=8,command=lambda:checker(button8))button8.grid(row=2,column=2,sticky=S+N+E+W)tk.mainloop()

   • error in python recursive code, to find palindromic primes in user inputted interval

     Top Answer

     Answered Sep 05, 2021 · 0 votes

     you can use recursion to iterate through the range of number by spliting that range in two and adding the left and right side results together

     When you get to a single value range, you process it to check that it is a palindrome (faster than checking if it is prime) and use recursion to check if it is also a prime number.

     You can check for primality recursively by passing a divisor as a defaulted parameter. The first iteration can check if the number is divisible by 2, then recurse to check if it is divisible by 3, 5, 7, 9 ... (odd numbers). Once your divisor is greater than the square root of your number, then you know that it is a prime number and a palindrome. This ends the recursion and returns the number as a one element list (which will be added to the others by the recursive iteration over the range of numbers)

     def paloPrimes(first,last,prime=2): # recursive iteration from first ro last if first<last: mid = (first+last)//2 return paloPrimes(first,mid) + paloPrimes(mid+1,last) # now only have one value to check if prime==2: # check palindrome if first < 11 or str(first) != str(first)[::-1]: return [] if first%prime == 0: return [] # not a prime if prime*prime < first: return paloPrimes(first,first,prime+1+prime%2) # recurse for primality return [first] # return palindromic prime number

     output:

     print(paloPrimes(10000,20000))-[10301, 10501, 10601, 11311, 11411, 12421, 12721, 12821, 13331, 13831, 13931, 14341, 14741, 15451, 15551, 16061, 16361, 16561, 16661, 17471, 17971, 18181, 18481, 19391, 19891, 19991]

     There is a limit to the recursion depth in Python so the size of the range and the magnitude of the numbers will be constrained (e.g. paloPrimes(3998992,3998994)) This function will use a depth of roughly log2(last-first) + √(last/2)

   Are all Python exceptions errors?

   What is a user-defined exception in Python?

   • Such a type of exception is called a user-defined exception or customized exception. The user can define custom exceptions by creating a new class. This new exception class has to derive either directly or indirectly from the built-in class Exception. In Python, most of the built-in exceptions also derived from the Exception class.
