Simplify counting and appending to a list


Simplify counting and appending to a list

I think the issue was by ths following , You can do this in two lines using collections.Counter (basically a special dict designed for counting things) and list comprehensions (a more concise syntax for writing simple loops).
Here's how I'd do it.

help you fix your problem I'm just learning about python. I'm fairly new.
code :
row[-3], row[-4] = 'http://www.foo.com/' + row[-3], 'http://www.foo.com/' + row[-4]

this will help I am trying to create a list in Python with values pulled from an active excel sheet. I want it to pull the step # value from the excel file and append it to the list while also including which number of that element it is. For example, 1_1 the first time it pulls 1, 1_2 the second time, 1_3 the third, etc. My code is as follows... , This line:
code :
if str(int(xl.Cells(i,1).value))+('_1' or '_2' or '_3' or '_4' or '_5' or '_6') in Steps:
in_list = [1, 1, 1, 2, 3, 3, 4]
from collections import defaultdict

tracker = defaultdict(int) # defaultdict is just a regular dict with a default value at new keys (in this case 0)
steps   = []

for cell in in_list:
    steps.append('{}_{}'.format(cell, tracker[cell]+1)) # This is +1 because the tracker starts at 0
    tracker[cell]+=1
 >>> steps
 ['1_1', '1_2', '1_3', '2_1', '3_1', '3_2', '4_1']

I think the issue was by ths following , I'm very new to Python and I've made a program which asks a user to select 2 numbers. The first must be between 1 and 10 and the second must be between 100 and 200. The program then asks the user to select a 3rd number between 1 and 5. Call these 3 numbers X, Y, and Z respectively The program then counts from X to Y in steps of Z. , You can replace the loop with:
code :
for q in range(x,y,z):
    print(q)

will be helpful for those in need I have this code and I want to write it using streams. I need to check if hList contains all dFoods elements.
code :
dFoods.stream()
  .allMatch(df -> 
      hList.stream
        .anyMatch(hl -> df.Name.equals(hl.title) && df.Timestamp.equals(hl.time)))
