Python execution problem from cpp shared object /u/Rough_Metal_9999 Python Education

Python execution problem from cpp shared object /u/Rough_Metal_9999 Python Education

I have a python program that loads a .so file generated with cpp code in the code i expose a function that executes a simple hello world program

everything works fine when i run cpp program it executes and prints hello world

when i make so file , and call the same function from .py file and run the py file it gives me error of

<code>

free(): invalid pointer
zsh: IOT instruction (core dumped) python3 main.py

</code>

i use cout statement to find out the problem occur while initilising python Py_Initialize(); in this method

itry to execute the function call with another thread same error occour

​

Why this happend and how i solve it

I’m struggling with learning python /u/Affectionate_Play180 Python Education

So I have been taking this python class at WGU and it’s killing me. The way the course is set up is very odd and incoherent IMO. I feel like I need a deep dive on the basics. Are there any books or courses (preferably Udemy because I get them for free) that would help a beginner? Any advice or suggestions would be greatly appreciated.

Can you filter pandas dataframes by Day/Month date without year? Writing a generalised function for between date that is year agnostic is proving difficult. /u/Statnamara Python Education

Can you filter pandas dataframes by Day/Month date without year? Writing a generalised function for between date that is year agnostic is proving difficult. /u/Statnamara Python Education

Ths issue stems from using year agnostic dates. If I want to return dates between June 15th – Sep 15th for every year it seems I need to manually write

df[“date_col”].dt.month.eq(6) & df[“date_col”].dt.day.ge(15) df[“date_col”].dt.month.between(7,8) df[“date_col”].dt.month.eq(9) & df[“date_col”].dt.day.le(15)

This doesn’t generalise well. Writing a function that takes a min and max date has a lot of different edge cases, i.e. dates are in the same month, dates are in consecutive months, dates cross a new year, etc.

A big part of the problem is that pd.to_datetime(“1506”, format = “%d%m”) returns Timestamp(‘1900-06-15 00:00:00’) and is therefore very much NOT year agnostic.

Issue raising exceptions – Beginner project /u/benmilesrocks Python Education

Issue raising exceptions – Beginner project /u/benmilesrocks Python Education

Hi everyone!

Trying to make a simple code to handle exceptions. The task is to make a piece of code that checks if an inputted number is between a specified range (in this case -10 to 10). I can make it handle an exception if it falls out of the range, no problem. But I also need a ValueError exception if somebody inputs non numeric values. But I can’t make the ValueError exception work for some reason. Here’s the code:

def read_int(prompt, min, max): try: if prompt in range(min, max): return str(prompt) if prompt not in range(min, max): raise IndexError except IndexError: return “Error: Value not in range ” + str(min) + “, ” + str(max) except ValueError: return “Error: Wrong input” v = read_int(int(input(“Enter a number from -10 to 10: “)), -10, 10) print(“The number is:”, v)

v = read_int(int(input(“Enter a number from -10 to 10: “)), -10, 10)

print(“The number is:”, v)

I’m certain that it’s something REALLY basic that I’m missing here, but I can’t figure it out for the life of me. Please help!!

Problems with using list /u/Easy-Paramedic-5611 Python Education

Problems with using list /u/Easy-Paramedic-5611 Python Education

Alright, basically. I am working on a random script to “find clothes” and clothes are in a list. So we got shoes and all such, in a list. All though i can’t seem to figure out how to print only one of the elements in the list. I originally used “` random.choice(clothes) “` but then i couldn’t figure out how to remove that option from the list, because if that is a choice i’d do that instead
