The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less.
Answer:
This is one of the efficient ways to find the number of occurrences of a given number in a list:
<h3><u>def find_num(arr,n):</u></h3><h3><u> return len([count for count in arr if count == n])</u></h3><h3><u>print(find_num([0,1,1,1,0],1))</u></h3>
If you want a simpler version, you can try this:
<h2><u>def find_num(arr,n):</u></h2><h2><u> count = 0 </u></h2><h2><u> for i in range(len(arr)): </u></h2><h2><u> if arr[i]==n: </u></h2><h2><u> count += 1 </u></h2><h2><u> return count</u></h2><h2><u>print(find_num([0,1,1,1,0],1))</u></h2>
This is the simplest method:
<h2><u>
arr = [0,1,1,1,0]</u></h2><h2><u>
print(arr.count(1))</u></h2>
I think I gave you enough examples. This should get you started off easily.
If you need an explanation, I am happy to help you. BTW I started python 6 months back so even I am pretty new to this.
Answer:
4 Platters
Explanation:
The capacity of one platter
= 1024 x 2048 x 4096
<em>1 platter capacity= 8GB
</em>
For a 30GB hard disk, we need
30/8 = 3.75 platters.
<em>we round off the answer so 4 platters will be required.</em>
Answer:
recognition
