Here is a simple example of getting the filenames inside of a given directory and displaying them as buttons to be selected from. This example will only work with a directory containing only text files but it should serve to provide a good example. Here I use the os import and use the method from … Read more
That’s because although you call the function you don’t save its return value anywhere. Try instead def main(): price = equation(5, 10) print(price) Note also that the variable in the calling function doesn’t need to relate to naes inside the called function (which are generally only available inside the function). So you could equally well … Read more
Would overriding func1 work? class Class(file1.Class2): def func1(self): print “Class3.func1” c = Class3() c.func2() Since func2 is not defined in Class3, Class2.func2 is called. However, in the body of that function, self is still an instance of Class3, so self.func1() calls Class3.func1, not Class1.func1. That is different from d = Class2() d.func2() where self in … Read more
Introduction Sets are a powerful tool in Python that can be used to find common letters between two strings. Sets are unordered collections of unique elements, meaning that each element can only appear once in a set. This makes them ideal for finding common letters between two strings, as each letter can only appear once … Read more
Introduction Python is a powerful programming language that allows you to manipulate data in a variety of ways. One of the most common tasks is to convert a string to a tuple. A tuple is a data structure that is similar to a list, but it is immutable, meaning that once it is created, it … Read more
Pythons re module does not support variable length lookbehind. Simple fix, avoid using lookaround assertions.. m = re.findall(r'(?s)Credit\s*(.*?)Amount’, lines) 3 solved value not found and look behind errors
Your base case is return 0. After the line return n * bounce(n – 1) where n is 1, bounce(0) will be executed, returning 0 and multiplying all your previous results by 0. Following the calls, we see: 5>=1, so return 5*bounce(4) 4>=1, so return 5*4*bounce(3) 3>=1, so return 5*4*3*bounce(2) 2>=1, so return 5*4*3*2*bounce(1) 1>=1, … Read more
httplib is for the job, and you may refer to the example code at the bottom of the document. and google for the httplib sample code. 1 solved Python: I need a code to auto login a website with HTTPS [closed]
The declaration of your globals is wrong. You declare your globals as a description of how they should be calculated. That will just not work. The global keyword in python is used to bring a variable in the local scope. Then you can alter it. Like this: def updateGlobals(): global global_variable global_variable = “new value” … Read more
For this example, I used your two lines of input data pasted three times in the data.txt input test file: Python: import re data = {} regex = re.compile(r’CustomerId:(\d+).*?Size:(\d+)’); with open(‘data.txt’) as fh: for line in fh: m = regex.search(line) if (m.group(1) and m.group(2)): cust = m.group(1) size = m.group(2) try: data[cust] += int(size) except … Read more
I think your understanding of what an instance is wrong here, since everything is an object in python, so 5 is an object of class int and [2,3] is an object of class list and so on. isinstance(x, y) is the way to go if you just want to check if x is an object … Read more
In your above algorithm, if the length of your array is 5, it will execute the inner if statement 25 times. In general when you will have a list of n size, it will for sure do n^2 operations excluding the for loop and swapping. For a list of size 10^6, it will be 10^12 … Read more
