[Solved] Cython interfaced with C++: segmentation fault for large arrays
The memory is being managed by your numpy arrays. As soon as they go out of scope (most likely at the end of the PySparse constructor) the arrays cease to exist, and all your pointers are invalid. This applies to both large and small arrays, but presumably you just get lucky with small arrays. You … Read more

[Solved] What are the thousands of lines in error in python
This is a stack trace. It shows not just where the actual error occurred directly, but also what the program was doing while it occurred. The code df.loc[‘origin’ == ‘US’] (on line 6) is at the top of the trace, meaning it’s the root cause, but this by itself is not an error. This will … Read more
[Solved] How can I remove the single quotes from a string and use it for division in Python?
Python has an eval() function that can do this: a = “https://stackoverflow.com/” b = “6” c = “3” print eval(b + a + c) However, please note that if you’re getting input from a remote source (like over a network), then passing such code to eval() is potentially very dangerous. It would allow network users … Read more
[Solved] Python script to find nth prime number
This can be a start. This checks whether the number N is divisible by all numbers from 2 to int(sqrt(N)) + 1, where the int function truncates the square root of N. The all() function in python returns True if all members of a list satisfy some condition (here not zero). You should set an … Read more
[Solved] Need help understanding a type error
Replace last main() with main(game) and make this small changes, remember to read the python tutorials, good luck! import random import math game = int(input(“How many problems do you want?\n”)) num_1 = random.randint(1,10) num_2 = random.randint(1,10) def main(game): random.seed() count = 0 correct = 0 result = 0 #Here we initialized result to 0 while … Read more
[Solved] npm install error though Python already included [duplicate]
The build fails because you are using Windows instead of Linux. This is clearly stated in the installation instructions you claim to have followed. notes The build tasks rely on Linux shell commands such as pkill and rsync so are unlikely to run on other OS’s without some tweaks. If you want to run this … Read more
[Solved] how to get the time after two minutes [closed]
To get the date-string in bash: echo “Current: ” $(date +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) echo “+2 min : ” $(date –date=”@$(($(date +%s)+120))” +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) prints Current: 2014-09-10T15-58-15 +2 min : 2014-09-10T16-00-15 Read the time from string and print +2min string str=”2014-09-10T15-58-15″ new=$(date –date=”@$(($( IFS=”-T” read y m d H M S <<< “$str”;date –date=”$y-$m-${d}T$H:$M:$S” +%s )+120))” +”%Y”-“%m”-“%d”T”%H”-“%M”-“%S”) echo “From … Read more
[Solved] Dictionary comprehension to compare two dictionaries [closed]
Create an intersection of the keys, then access the value in both dictionaries: {k: dict1[k] * dict2[k] for k in dict1.viewkeys() & dict2} This uses dictionary views which act as sets (and & creates a set intersection). In Python 3 you get dicitonary views via the default methods: {k: dict1[k] * dict2[k] for k in … Read more
[Solved] Python – keeps reporting a syntax erro on the ‘elif’ statement
I agree that you should consider changing your single line comments to use the pound symbol. I ran your code and once I indented the multiline comments, the syntax error disappeared. As the other answers mentioned, following an if statement, the compiler expects either once-more indented code or an elif statement or new code at … Read more
[Solved] Is there a way in python to compare strings for unique character [closed]
Assuming Benoît Latinier’s interpretation of your question is right (which, it looks like it is), then there will be some cases where a unique letter can’t be found, and in these cases you might throw an exception: def unique_chars(words): taken = set() uniques = [] for word in words: for char in word: if char … Read more
[Solved] How to write a python code on checking an arithmetic progression? [closed]
You can pair adjacent numbers, calculate the differences between the pairs, and determine that the list forms an arithmetic progression if the number of unique differences is no greater than 1: from operator import sub def progression(l): return len(set(sub(*p) for p in zip(l, l[1:]))) <= 1 so that: print(progression([3])) print(progression([7,3,-1,-5])) print(progression([3,5,7,9,10])) outputs: True True False … Read more
[Solved] Indentation error in python, how do I check for spaces or tabs to avoid the error? [duplicate]
From the documentation: Indentation is rejected as inconsistent if a source file mixes tabs and spaces in a way that makes the meaning dependent on the worth of a tab in spaces; a TabError is raised in that case. You state the body of the with statement is indented with 3 tabs. If that is … Read more
[Solved] Why does looking up an index *before* a swap rather than inline change the result?
Let’s add some tracing so we can see order-of-operations: import sys def findIdx(ary, tgt): retval = ary.index(tgt) print(‘First instance of %r in %r is at position %r’ % (tgt, ary, retval), file=sys.stderr) return retval data1 = [1.48, -4.96] i = 0 mn = data1[1] k = findIdx(data1, mn) data1[i], data1[k] = data1[k], data1[i] print(“Prior lookup: … Read more
