Sorting list items considering unit’s place. You can try: list1 = [1236,985,150,641876,167] sorted(list1, key=lambda n: n%10) [150, 985, 1236, 641876, 167] solved How to sort sum digits from the following list [closed]
You can assign the result of the value_counts() to a Series and filter it as below: count = df_1[‘neighbourhood’].value_counts() ax = count[count > 2000].plot(kind=’bar’, figsize=(14,8), title=”Neighbourhood that showed”) ax.set_xlabel(“neighboorhood”) ax.set_ylabel(“Frequency”) solved I want to plot the count of over a specific number e,g 2000 [closed]
I’d suggest using python print function print(“”) At multiple locations to actually see the recursion happening. You would get a better idea than someone trying to explain it to you. Although the function itself is quite simple. For every element in distances, the function subtracts the element from the required r value and checks the … Read more
Assuming you have an input that looks like this:dic={x:[a,b],y:[c]}. Try this, res=sorted([(x,len(dic[x])) for x in dic],key=lambda x:x[0]) solved How to compare number of values in a dictionary [closed]
For generating a list from 1 to n, we use range In [8]: n = 10 In [9]: for i in range(1,n+1): …: print(i) …: 1 2 3 4 5 6 7 8 9 10 Building on this, to generate the string you want from 1 to n, we do as follows, we build the … Read more
writing the simulation is easy – im having trouble figuring out the optimization, i tried .4 to .1 for the pct multiplier and alway made over 1 billion in well less than 1000 tries: from random import randint x = 1.0 # 1 euro pct = .25 # 1/4 for i in range(1000): # 0-999 … Read more
If you need to compare with other members, don’t use the for-each loop. for i in range(len(states_list)): if i > 0: if states_list[i][0] != states_list[i-1][0]: print(‘\n’) print(states_list[i]) 2 solved How do I print a blank line whenever the first letter of the state differs from the previous state’s first letter [closed]
I feel you should try to fully master one language before advancing to another. If you juggle too many at the same time you will just mix up their syntax and spend a lot of time becoming a jack of all trade and a master of non. 6 solved Should I learn C++ before I … Read more
The source of the error is on line 3 script, first, second, third = argv. argv is a way of seeing what extra information is being given to your program. When you call your program with python section12.py, argv is defined as (“section12.py”,). When you call your program with python section12.py 65, argv is defined … Read more
def item_order(order): new_order = order.split() sal = 0 wat = 0 hum = 0 for a in range(len(new_order)): if new_order[a] == ‘salad’: sal = sal + 1 elif new_order[a] == ‘water’: wat = wat + 1 elif new_order[a] == ‘hamburger’: hum = hum + 1 return (‘salad:’ + str(sal) + ‘ ‘ + ‘hamburger:’ + … Read more
You are multiplying a list by a float. You should multiply each row of the matrix with words. Something like this will work. multiply_nonspam_test = [] for row in transpose_test_feature: multiply_nonspam_test.append([x*y for x,y in zip(row, log_train_probs_nonspam_words)]) print multiply_nonspam_test 0 solved can’t multiply matrix and list which type ‘float’
Your immediate problem is this: LDates[‘%s’ % (‘string%s'[‘Id’] % i)] I believe that you mean to access the variable you created earlier. That would require you to use: LDates[(globals()[‘string%s’ % i])[‘Id’]] But this whole thing is ill-advised. Why don’t you create a variable where you can access all the data by just passing in the … Read more
You have asked a lot of questions under one! I will try to answer each of those 🙂 Variables – global vs local global variables are those ones whose scope is global, i.e. available in entire program. local variables by contrast are those ones which resides in one particular scope, a function, inside a loop, … Read more
Disregarding the myriad of syntax errors, your myarray variable seems to be declared globally and that’s why it has global scope? 4 solved Why Python scope my variable outside my function?
You had most of the elements correct in your script, but you need to think more about the order of everything. Make sure you pass any arguments that are needed to a function. Your getAvg function needed three arguments for it to calculate the average and display it with the student number. Also you forgot … Read more
