This will search for the separator in the string. If the separator is found, returns a 3-tuple containing the part before the separator, the separator … Read more

Your current approach won’t work for the time constraint – it’ll just take too long to complete. Try this code first and figure out what’s the trick to save computing time. primes = [2,3,5,7,11,13,17,19] prod = 1 for p in primes: n = 2 prod *= p while (p**n < 21): prod *= p n … Read more
The way you are taking input is wrong When you do this s[i][j]=int(input()) you are converting two space separated ints to a single int def avg(s,n): sum1=0 sum2=0 for i in range(0,n): for j in range(0,2): if j%2==0: sum1+=s[i][j] else: sum2+=s[i][j] print((float)(sum1/n)) print((float)(sum2/n)) n=int(input()) c=2 # I am going to ask for user input n … Read more

Maybe something like this: lines = int(input(‘How many lines?: ‘)) starCount=”*” for i in range(lines): print(starCount) starCount *= 2 solved Expotential growth of symbols in python?
In python, tuples are defined with tup = (val1,val2,…). This is what you’re doing when you define wholeAssDocumentation. Since tuples don’t have a re method, you’re getting that error. Other than that, I suggest you read the regex documentation because that’s not how you use a regex on a string either. Also you’re overwriting the … Read more
with open(‘foo.txt’, ‘w’) as f: for i, array in enumerate([Array_1, Array_2]): for s in array: print(f'”{s}”‘, i, file=f) Where ‘foo.txt’ is the path to your text file. 1 solved How to use python join the arrays and specify from which array?
If you want to do it your way: for i in range(1, 21): print(i, end=”,” if i!=20 else “” ) Output: 1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20 But a better way of doing this would be: print(*range(1, 21), sep=”,”) solved How to remove the last comma?
I think you need Series.cumsum with select last row (total row) by DataFrame.iloc: df = pd.DataFrame({ ‘B’:[4,5,4], ‘C’:[7,8,9], ‘D’:[1,3,5], ‘E’:[5,3,6], }) df.loc[‘sum’] = df.sum() df.loc[‘cumsum’] = df.iloc[-1].cumsum() #if need only cumsum row #df.loc[‘cumsum’] = df.sum().cumsum() print (df) B C D E 0 4 7 1 5 1 5 8 3 3 2 4 9 5 … Read more
Trick The trick is to find out in advance whether a target_key is among the next children (= this_dict[key] = the values of the current dict iteration) before you reach the child level recursively. Only then you can still delete a key:value pair of the child level while iterating over a dictionary. Once you have … Read more
