Python, one of the most versatile programming languages, is popular for data science applications, as well as web development, offers various ways to implement loops, particularly the for loop. This explainer w
What is for loop in Python In Python, theforloop is used to iterate over a sequence such as alist, string,tuple, other iterable objects such asrange. With the help offorloop, we can iterate over each item present in the sequence and executes the same set of operations for each item. ...
Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function works really well. When working withrange(), you can pass between 1 and 3 integer arguments to...
In Python, we use indentation (spaces at the beginning of a line) to define a block of code, such as the body of a loop. For example, languages = ['Swift', 'Python', 'Go'] # start of the loop for lang in languages: print(lang) print('---') # end of the for loop print...
In Python, the “one line for loop” is used to perform multiple operations in a single line which reduces the space and amount of code. The “list comprehension” used “one line for loop” to apply an operation on its own elements with the help of the “if condition”. The “list ...
Let's consider another example of a for loop, where you make use of two variables to define your control flow: languages = ['R', 'Python', 'Scala', 'Java', 'Julia'] for index in range(len(languages)): print('Current language:', languages[index]) Powered By Current language: R...

b[3] = 3; b[4] = 4; . It is hard for the compiler to unrollfor loopin the neuron's kernel because the i-th calculation depends on (i-1)-th calculation. But we can use python to unrollfor loop. Here is an example: formem_offsetinrange(0,numel,neuron_num):code+=rf'''t ...
