Answer:
false true
Explanation:
In the code snippet, two string objects are created in java with the value Java.
The print method first checks the condition s1==s2 and outputs false, This is so because the operator == which is used for equality in other primitive data types like ints cannot be applied to the String data type. In the second part of the print function, the equals function s1.equals(s2) is used and it prints true since the two string are equal
nums = [x*1.5 for x in range(1,11)]
print(nums)
The first line is the list comprehension and the second prints the list to the screen so you can see that it works.
Answer:
#section 1
def maxTemp(filename):
import pathlib
f = pathlib.Path(filename)
f.exists()
if f.exists():
f = open(filename, "r")
#section 2
next(f)
res = [int(sub.split(',')[1]) for sub in f]
maxdata = (res[0])
for i in range(len(res)-1):
if maxdata < res[i]:
maxdata = res[i]
index = res.index(maxdata)
f.close()
#section 3
li = []
a = open(filename, "r")
for line in a:
line = line.strip()
li.append(line)
a.close()
return (li[index+1])
else:
return -1
print(maxTemp("new.csv"))
Explanation:
#section 1:
The function maxTemp is defined. We import pathlib in other to check if the file exists, if it does we carry on with opening the file and if it doesn't the program returns -1.
#section 2:
We start splitting the sub-lists from the second line i.e <em>next(f)</em>. For each line we take the second index element and convert it to an integer.
<em>res = [int(sub.split(',')[1]) for sub in f]
</em>
The maximum number is gotten by using the if statement to compare all elements in the list. The index of the maximum item in the list is collected.
the file is then closed.
#section 3 :
The file is re-opened and all the lines are striped and passed into a new list and the index recovered from section 2, is used to get the day with the highest temperature and the line is returned.
Answer:
C
Explanation: This is because not every area is structured on the same ground as other places.
