You caniterate arrays using for loopto access each string present in the array. You can use a for loop in Python over the sequence or iterable objects such as lists,sets,strings,tuples, anddictionariesto perform various operations in Python. # Iterate array of stings using for loop # get ...
In Python, you can create a list of zeros using many ways, for example, for loop,itertools.repeat(), list comprehension,bytearray, andnp.zeros()functions. In this article, I will explain how to create a list of zeros by using all these methods with examples. 1. Quick Examples of Crea...
It is similar to an array in other programming languages with a little difference. While a list can store heterogeneous elements, an array can’t. The elements of the list are enclosed within square brackets. A list is a mutable data type in Python. A mutable data type can be changed aft...

In the above example, we are trying to read only the 4thline from the ‘test.txt’ file using a“for loop”. Output: Reading the entire file at once filename = “C:/Documents/Python/test.txt” filehandle = open(filename, ‘r’) ...
Inside the loop body, we: Print out the name of the array element at the current index. Increment thepet_indexvalue by one in preparation for the next loop iteration. Both methods for looping over an array in Python do the same. Whichever method you use is up to your own personal prefe...
The file contents are stored in the reader.result object as one giant string with embedded ‘\n’ characters. The String.split function is used to extract each line into an array. Then the lines are iterated through using a for-loop with the length property. Next: ...
If the call site is being run for the first time, it generates a DynamicMethod that returns an object and takes an object array as an argument. The object array argument contains the instance object and the arguments that are to be used for the final call to t...

The first method involves the range() function to create a sequence and convert it to a list using the list() function. The numpy.arange() function creates the sequence in an array, and we can convert this to a list with the tolist() function. We can also use the for loop for ...
