Write a program that reads the student information from a tab separated values (tsv) file. The program then creates a text file that records the course grades of the students. Each row of the tsv file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student. A sample of the student information is provided in StudentInfo.tsv. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
Read the file name of the tsv file from the user.
Open the tsv file and read the student information.

Compute the average of each exam.
Output the last names, first names, scores, and letter grades of the students into a text file named report.txt. Output one student per row and separate the values with a tab character.
Output the average of each , with two digits after the decimal point, at the end of report.txt. Hint: Use the format specification to set the precision of the output.

let us consider a simple 20. m2 rooftop installation of crystalline-silicon (c-si) pv modules. remember that pv modules are rated to receive 1.0 kw/m2 of solar radiation. assuming peak solar irradiance of 1.0 kw/m2, what would the peak output of this system be (in kw) if the modules are 18% efficient? [2 points]
The peak output of the system would be 18% * 20 kW = <<18*.01*20=3.6>>3.6 kW. Thus, the peak output of this system be \boxed{3.6} (in kw) if the modules are 18% efficient.
PV modules are photovoltaic modules, which are units made up of multiple photovoltaic cells. These modules are used to convert sunlight into electricity. They are a key component in solar power systems, and are often used to power homes and businesses. The electricity generated by PV modules can be used immediately, or it can be stored in a battery for later use.
If a 20 square meter rooftop installation receives 1.0 kW/m^2 of solar radiation, the total amount of solar radiation it receives is 20 * 1.0 = <<20*1.0=20>>20 kW.
Since the modules are 18% efficient, the peak output of the system would be 18% * 20 kW = <<18*.01*20=3.6>>3.6 kW. Answer: \boxed{3.6}.
