Code is Outputting Incorrectly

[mikerosz94]

The code shown below is outputting everything on my CSV sheet. It's not suppose to do that. Instead, the goal is to match Year and data_location, which finally prints the information in that row. So for example if I input:
Year=1
data_location=1
Desired output should be:

Output:
Busnum:126688 busname:B New Load:125

Output:
Busnum:126695 busname:m New Load:85

Output:
Busnum:126696 busname:O New Load:77

LOAD_GEN_DATAFILE = 'C:\Users\RoszkowskiM\Desktop\Data_2017.csv' # CSV File to Read


# read the entire CSV into Python.
# CSV has columns starting with Year,busnum,busname,scaled_power,tla,location

# read the entire CSV into Python.
# CSV has columns starting with Year,busnum,busname,scaled_power,tla,location
