column += 1 can not be used in the way you are using it because it is a statement rather than an expression. What you are writing is equivalent to self.test1 = input[column = column + 1] which doesn’t much sense. Instead you would need to do: column += 1 self.test1 = input[column] or self.test1 … Read more
I don’t know about sed or R, but in Python: >>> import re >>> i = “””NOTE: Variable Variable_S1 already exists on file D1.D, using Var_S8 instead. NOTE: The variable name more_than_eight_letters_m has been truncated to ratio_s. NOTE: Variable ratio_s already exists on file D1.D, using Var_S9 instead.””” >>> print(re.findall(r'(\w+_\w+)’, i)) [‘Variable_S1’, ‘Var_S8’, ‘more_than_eight_letters_m’, ‘ratio_s’, … Read more
Print them recursively: def gen_num(trailing, depth, left): if depth < 11: for i in range(max(0,min(10, left))): gen_num(trailing*10+i, depth+1, left-i) elif depth == 11: if left < 10: print trailing*10+left for i in range(1,10): gen_num(i, 1, 55-i) solved How to generate a 12 digit number, but all the digits summed together must equal 55?
You can use a dict to store the results of your die rolls in a much simpler fashion. This will allow you to loop over all the results instead of writing a separate print statement for each. It also simplifies your code a lot! For example: import random results = {1:0, 2:0, 3:0, 4:0, 5:0, … Read more
Why do you assert that a+b is not equal to a+b? Do this: assert f.summ(self.a, self.b) == self.a + self.b 1 solved Why is this Python test failing? [closed]
The reason for this is that every counter(7) call creates a separate count instance and separate incr function. When you call them, you actually refer to different variables count thus the results are as shown above. 2 solved Below code is weird
It seems you have two unrelated questions here. The first is whether your calculateTutitionIncrease function does the right thing to create an list of cost values over time. It is not bad, exactly, but it could be better. To start with, you could use a for loop over a range, rather than a while loop … Read more
Given the following dataframe: df = pd.DataFrame({ ‘B’: [‘a’, ‘a’, ‘c’, ‘d’, ‘a’], ‘C’: [‘aa’, ‘bb’, ”, ‘dd’, ‘do’], }) B C 0 a aa 1 a bb 2 c cb 3 d dd 4 a do value_counts method counts the occurrences of all values in column ‘B‘: df.B.value_counts() a 3 d 1 c 1 … Read more
>>> lst = [6,12,8,9,1,18,24] >>> print([value for index,value in enumerate(lst) if index%6==0 and value%6==0]) [6 , 24] solved How to do list comprehension that display a list elements whose elements and index are divisible by 6?
It’s not possible. The best solution will be using a function with *args and possible **kwargs: argsneeded = [‘foo’, ‘bar’] def whatever(**kwargs): if not all(x in kwargs for x in argsneeded): raise ValueError(‘required kwarg is missing’) 0 solved Python: How to get names of arguments in a list in a lambda?
Option 1 The simplest and most direct – use the str accessor. v = df.ID.astype(str) df[‘Year’], df[‘ID’] = v.str[:4], v.str[4:] df DateTime Junction Vehicles ID Year 0 2015-11-01 00:00:00 1 15 1101001 2015 1 2015-11-01 01:00:00 1 13 1101011 2015 2 2015-11-01 02:00:00 1 10 1101021 2015 3 2015-11-01 03:00:00 1 7 1101031 2015 4 … Read more

N1 is simply just a list of names (that are of type String). When you loop / iterate over your list (for names in N1), each loop iteration will then act on that index of the list. So for the first iteration of the loop, names is equal to Ryan and therefore since you are … Read more
Try invalidating your caches by going to File > Invalidate caches / Restart and then wait for your code to be re-indexed. solved What is a good opening time for an IDE (Pycharm)?
Here are few quick points I noticed: 1.Indentation issue for the if statement in the age condition. This if statement should ideally be within the if statement of gender==f. The way python requires you to write/use “and” condition. You can look at the syntax here https://www.learnpython.org/en/Conditions If someone enters an age out of the range … Read more
