 All built-in functions https://docs.python.org/3/library/functions.html#eval a // b = The integer part of the integer division of a by b a ** b = Elevates a to the power of b. For non integer values of b, this becomes a root (i.e. a**(1/2) is the square root of a) Character Meaning 'r' open for reading (default) 'w' open for writing, truncating the file first 'x' open for exclusive creation, failing if the file already exists 'a' open for writing, appending to the end of file if it exists 'b' binary mode 't' text mode (default) '+' open for updating (reading and writing) The default mode is  'r'  (open for reading text, a synonym of  'rt' ). Modes  'w+'  and  'w+b'  open and truncate the file. Modes  'r+'  and  'r+b'  open the file with no truncation.

 Last day interview preparation strategy 💯 - For Tech interviews only for SDE-1 role or intern: ✨ I have listed down some main topics to have a look for the last day before interview for SDE role, though its for those who are freshers going for FTE role or internship interview 👇. 1️⃣ Main topics of DSA - Graphs(DFS,BFS mainly), Trees 🌴, DP(1D,2-D mainly). 2️⃣ OOPS - singleton pattern and it's usage, virtual function concept ,inheritance(diamond problem). 3️⃣ DBMS - Normalisation concepts, indexing, transactions, concurrency control concepts,SQL queries revision 4️⃣ OS - file management, process scheduling algos, memory management, synchronisation concepts involving locks(most important 🤞)and semaphores. 5️⃣ CN - network topology concepts, VPN concepts , IP concepts, OSI Model(important). This strategy does not give guarantee for 100% but it's better to study only few important topics on last few days before interview schedule, I found these topics asked majorly by companies...
