Python iftest_expression:# statement(s) to be run For example: Python a =93b =27ifa >= b: print(a) Output:93 In Python, the body of anifstatement must be indented. Any code following a test expression that isn't indented will always be run: ...
If/then/elif –This is the most common kind of conditional statement in Python. The compiler uses the if statement to check if something is true or false in code and then only executes another block if it is true. For example: if 1 == 1: print('Yes') if 2 == 2: print('No')...
So far, we have presented a Boolean option for conditional statements, with eachifstatement evaluating to either true or false. In many cases, we will want a program that evaluates more than two possible outcomes. For this, we will use anelse ifstatement, which is written in Python aselif....
In this article, I will explain the following ways of Python to write a for loop in one-line code with examples. Simple One Line For Loop Using List Comprehension List Comprehension with if-else statement Usingnested For Loops Nested For Loop with condition Nested For Loop with Multiple condit...
Problem statement Suppose that we are given two NumPy arrays containing float and string values respectively. We need to stack these two arrays together and write them into a text file of columns. Using numpy.savetxt() to write strings and float number to an ASCII file ...

Syntax to close an open file in Python: fileobject.close() Copy If we continue on from our previous examples where we read files, here’s how you’d close the file: text_file=open('/Users/pankaj/abc.txt','r')# some file operations heretext_file.close() ...
Python Create and Open a File Python has an in-built function called open() to open a file. It takes a minimum of one argument as mentioned in the below syntax. The open method returns a file object which is used to access the write, read and other in-built methods. ...
There are two ways to write files in Python: Using the open() function: The open() function takes two arguments: the file name and the mode. The mode can be "w" for writing, "r" for reading, "a" for appending, and "rb" for reading binary data. Using the with statement: The ...
The typical way to deal with multiway branching inProgramminglanguages is the if-else clause. When we need to code numerous scenarios, an alternative is the so-calledswitchorcasestatement that is supported by most modern languages. For Python versions < 3.10 however, there was no such statement...
