[ad_1] You must first import random. To choose your image, do image = math_list.pop(random.randint(0,len(math_list)-1)). randint is used to choose a random number from 0 to 4, each one corresponding to an item in the list. pop removes that item and returns it to image. 8 [ad_2] solved How to blit a random image from a … Read more

[ad_1] I found a way to do what you are asking for: class AddableInt(int): def __call__(self, n): return AddableInt(self + n) def add(n): return AddableInt(n) add(5)(10)(20) # evaluates to 35 This works because the call to add(5) creates an AddableInt with a value of 5. No __init__ method was declared in AddableInt, so it just … Read more
[ad_1] Encapsulate the try/except blocks inside the while loop (not the other way around): while True: try: A() except NewConnectionError as err: # This will also print the reason the exception occurred print (‘Detected error: {}’.format(err)) else: print(“A() returned successfully.”) finally: print (“Next loop iteration…”) You can safely omit the else and finally blocks. I … Read more
[ad_1] Try this code: # Define a dict{} for key:value pairs ref_total = {} # Get Data from all rows for row in ws.rows: # Slice cells A,B from row tuple cell_A = row[:1][0] cell_B = row[1:2][0] reference = cell_A.value if reference in ref_total.keys(): ref_total[reference] += cell_B.value else: ref_total[reference] = cell_B.value for key in sorted(ref_total.keys()): … Read more
[ad_1] You can use reduce (functools.reduce in Python3) if the integer is non-zero >>> x = [False, False, False, 10, False, False] >>> reduce(lambda i,j:i or j, x) 10 You can use a generator expression also here >>> x = [False, False, False, 10, False, False] >>> (i for i in x if i!=False).next() 10 … Read more

[ad_1] Since you’re calling the script as follows: python removeparenthesis.py filename.xml the XML file name will appear under sys.argv[1]. Also, you’d need to use lazy matching in your pattern: r’\(\w*?\)’ # notice the ? A better pattern would be: r’\([^)]*\)’ 2 [ad_2] solved Python and regex to remove parenthesis in a file [duplicate]
[ad_1] Yes, it is possible to find modulo (p) and sequence value (y) for given number x, but it requires using floating-arithmetics logarithm. pow = Floor(Log2(x+1)) p = 1 << pow y = 1 + (x + 1) % p For initial period s (3 in your second example) pow = Floor(Log2((x + s – … Read more
[ad_1] You can install pip from the pypl database directly with just: pip install scipy or if you want a particular version pip install “scipy==1.00” you shouldnt ever need to install from a local drive 1 [ad_2] solved Meeting Error when I install scipy
