More Details about 98-381 Exam Topics
The first tested topic covers the concepts about constructing code segments that perform iteration and use branching statements. The second area focuses on the notions of code segments that perform the file output and input operations along with performing console input and output processes. The next part puts an emphasis on code segments using documents & comment strings and also covers the function definitions. The fourth topic talks about notions of syntax, runtime, and logic errors and as well handles the exception segment. After that, the fifth domain involves the concepts of performing the operations using built-in modules and solving complex computing problems. The last section evaluates the expression to identify the data type Python, performing data type operations, and selecting the appropriate operator to achieve the intended results.
What are the main topics of the Microsoft 98-381 exam?
It is highly recommended for those students who are preparing for this Microsoft exam to visit the official website and find out the information about all the topics that are included in its content. Speaking of the covered subject areas, you should train the following:
Perform Operations Using Data Types and Operators (20-25%):
This part includes the following areas:
- Evaluate an expression to identify the data type that Python will assign to each variable: The candidates should know how to identify data types, such as string, integer, float, and bool.
- Perform data and data type operations: The individuals’ abilities to convert from one data type to another, construct data structures, and perform indexing and slicing operations are measured in this domain.
Moreover, the test takers have to be skilled in determining the sequence of execution based on operator precedence and selection of the appropriate operator to achieve the intended result.
Perform Troubleshooting and Error Handlings (5-10%):
In this section, the applicants have to demonstrate their expertise in analyzing, detecting, and fixing code segments that have errors as well as analyzing and constructing code segments that handle exceptions.
Perform Operations Using Modules and Tools (1-5%):
The last topic is about your competence in built-in modules used to perform basic operations and solve complex computing problems.
Document and Structure Code (15-20%):
This topic is all about the students’ ability to use documentation strings and comments to document code segments construct and analyze code segments, which include function definitions, use indentation, comments, white space, and documentation strings, call signatures, and use pydoc to generate documentation.
Control Flow with Decisions and Loops (25-30%):
Here the learners have to show their knowledge of the construction and analysis of code segments that use branching statements and perform iteration. They should also know about the compound and nested conditional expressions, such as if, else, break, for, pass, while, continue, as well as nested loops and loops that include compound conditional expressions.
Perform Output and Input Operations (20-25%):
This section requires your ability to construct and analyze code segments that perform file input and output operations, such as open, close, read, write, append, check existence, and delete. The candidates’ skills in constructing and analyzing code segments that perform console input and output operations are evaluated as well. They should be able to read input from the console, print formatted text, and use command-line arguments.
Domain Operations through Modules and Tools
The last exam domain is the shortest of all. Only 1-5% of exam content is covered by it. It is designed to impart a foundational understanding about key operations through the in-built modules, knowledge of random, datetime, and math, and solving tedious computing problems.
NEW QUESTION 25
You develop a Python application for your school.
You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content must be removed.
Which code should you use?
- A. open("local_data", "r+")
- B. open("local_data", "w+")
- C. open("local_data", "w")
- D. open("local_data", "r")
Answer: B
Explanation:
Explanation/Reference:
Explanation:
Modes 'r+', 'w+' and 'a+' open the file for updating (reading and writing). Mode 'w+' truncates the file.
