Afile named numbers. txt contains an unknown number of lines, each consisting of a single integer. write some code that computes the sum of all these integers, and stores this sum in a variable name sum.

The code is given below with necessary comments for understanding

Explanation:

#Open the input file.

infile = open("numbers.txt", "r")

#Declare and initialize the required variable sum

#to store the sum of integers read from the file.

sum = 0

#Declare and intialize a variable to store the current

#number read from the file in the integer form.

curNum = 0

#Traverse the input file using for loop.

for curLine in infile:

   #Assign the number read from the file to the

   #variable curNum in the integr form.

   curNum = int(curLine)

   #Add the numbers read from the file to the

   #variable sum to get the sum of all the

   #numbers read from the file.

   sum += curNum

# Display the value of the variable runsum.

print(sum)

these  signals travel  down a part of the neuron called the axon, which is like a wire that carries the  signal  to othernerve  cells. on average a  nerve  cell sends a  signal  at about 50 meters per second, which is over 100  miles  an hour!
