Question

#Python

Help please

Modify the mistakes in my code , so that it prints the same statement four times. Using four distinct techniques—hard-coding, commas, concatenation, and string formatting. The hard-coding is already done. The other three techniques have been started but they contain mistakes. These techniques should each use all three of the provided variables. Once the mistakes have been corrected, run the script and upload a picture of the program running to make sure that it prints the statement identically four times:

Found 12 lights in the 5 mi. buffer and 20 intersections.

Found 12 lights in the 5 mi. buffer and 20 intersections.

Found 12 lights in the 5 mi. buffer and 20 intersections.

Found 12 lights in the 5 mi. buffer and 20 intersections.

Correct the mistakes in this script so that it prints the same statement 4 times, using 4 different methods:

1) hard-coding

2) commas

3) concatenation

4) string formatting

Code:

trafficLightsCount = 12
bufferDist = '5 mi.'
intersectionCount = 20

# 1) Entirely hard-coded statement. Don't change this one.
# Make the other print statements match this output.
print 'Found 12 lights in the 5 mi. buffer and 20 intersections.'

# 2) Modify the code to correctly use the three variables
# and use commas to join expression components.
print 'Found', trafficLightCount, lights in the intersectionCount buffer and, ' buffereDist' 'intersections.'

# 3) Modify the code to correctly use the three variables
# and use concatenation to join expression components.
print 'Found' + trafficLightCount + lights in the buffereDist buffer and intersectionCount intersections.'

# 4) Modify the code to correctly use ALL three variables
# and use the string 'format' method.
print 'Found {1} lights in the {0} buffer and 30 intersections.'format(trafficLightsCount, bufferDist)

If you have any doubts, please give me comment...

trafficLightsCount = 12

bufferDist = '5 mi.'

intersectionCount = 20

# 1) Entirely hard-coded statement. Don't change this one.

# Make the other print statements match this output.

print 'Found 12 lights in the 5 mi. buffer and 20 intersections.'

# 2) Modify the code to correctly use the three variables

# and use commas to join expression components.

print 'Found', trafficLightsCount, 'lights in the', bufferDist,'buffer and', intersectionCount, 'intersections.'

# 3) Modify the code to correctly use the three variables

# and use concatenation to join expression components.

print 'Found ' + str(trafficLightsCount) +" lights in the "+bufferDist +' buffer and '+str(intersectionCount)+' intersections.'

# 4) Modify the code to correctly use ALL three variables

# and use the string 'format' method.

print 'Found {0} lights in the {1} buffer and {2} intersections.'.format(trafficLightsCount, bufferDist, intersectionCount)
