You can use a string comprehension: numbers = [float(p.replace(‘€’,”).replace(‘M’,”)) for p in a] which gives: [110.5, 210.5, 310.5] solved Can i include multiple statements when creating a one-line for loop?
username = [‘admin’,’bill’,’Kevin’,’mike’,’nick’] while True : name =input(“Please enter a username: “) if name==’admin’ : print(“Hello “+ name + ” ,would you like to see a status report?”) break elif name in username : print(“Hello ” + name.title() + ” thank you for logging in!”) break else: print(“Who are you ” + name.title() + ” … Read more
You can use pandas: import pandas as pd l = [-1.5,-1,-1,0,0,-1,0,1.5,1,1,1,1,0,0,0,0,1,0,1,0,1.5,1,1,1,1,0,0,0,0,-1.5] s = pd.Series(l) cond1 = (s == 1.5) cond2 = (s == -1.5) cond3 = (s == 0) cond4 = ((s == 1) | (s == -1)) & (s.shift() == 0) out = pd.Series(pd.np.select([cond1, cond2, cond3, cond4],[1, -1, 0 ,0], pd.np.nan)).ffill() out.tolist() Output: [-1.0, … Read more
You don’t need to pass category_name, you only need the category id. The category name should be contained in each of the item fetched from the database. You’re getting an error because cat_id is not defined when the function def getCategoryItems(category_name, cat_id) is called. I would suggest, however, if you want to really get all … Read more
The solution is to pass the function as a lambda: from Tkinter import * root =Tk() def callback(parameter): print parameter button = Button(root, text=”Button”, command=lambda: callback(1)) button.pack() root.mainloop() Also, as @nbro already correctly pointed out, the button attribute is command, not function. 1 solved Tkinter Function attached to Button executed immediately [duplicate]
The Taylor series for the sin function is straightforward to implement. Note that any reference which gives a Taylor series for a trigonometric function will assume the input is in radians, unless specified otherwise. PI = 3.141592653589793238462643383 def sin_taylor_series(x, terms=9): # map x into the range -PI/2 to PI/2 for greatest accuracy x %= 2*PI … Read more
In C you need to add another “\” to your code like this. #include <stdio.h> main() { printf(“\\n”); } For Python you can use repr >>> string = “\n” >>> print(repr(string)) ‘\n’ 6 solved How do I print the characters “\n” instead of whitespace using python and C? [duplicate]
Division is defined so that the following is always true n = q × d + r where n is the numerator (or dividend), d != 0 is the denominator (or divisor), q is the quotient, and r > 0 is the remainder. (This holds for positive and negative values; q is positive if n … Read more
In the first line you have written first_quadrant as 1 which is an integer. In the second line you are trying to use a for loop over an integer. This is not allowed and therefore the error. You could do it in many other ways. I am writing two such possible solutions. Solution 1 first_quadrant … Read more
In order to give a complete answer as to why and what is happening here, first we need to talk about the concept of “scope”. Each function (and for loop, while loop etc) “lives in its own world” in terms of memory. What does that mean? Assume I have a function named “foo1” and another … Read more
Yes, it is very much possible. If you are a beginner, I recommend you use python to do this. You can use PyQt for your GUI, pyttsx and SpeechRecognition for the speech engine (offline). Do the following to install them: pip install SpeechRecognition pip install pyttsx Here’s some code to get you started on the … Read more
Restful web-service endpoints on each application makes reasonable sense based on the assumption you want to stick with Django/Python for this. I would suggest using Django Rest Framework and make use of token based authentication with pre-configured “shared keys” (which you can periodically rotate). With token-based auth, your keys are passed in the HTTP header … Read more
Building on larsmans answer, a custom iterator can be built to do this: class my_large_num(object): def __init__(self): self.num_iterations = 0 def __iter__(self): return self def next(self): if self.num_iterations < 1: self.num_iterations += 1 return 10**200 else: raise StopIteration() You can then: import pickle pickled_repr = pickle.dumps(my_large_num()) restored_object = pickle.loads(pickled_repr) sum(restored_object) This works because underneath, iterable … Read more
list1 is a list that contains 1 element that is an numpy.array that contains multiple floats64. list2 is list that contains 1 element that is a list that contains multiple strings (that happen to look a lot like floats). You can convert them like so: import numpy as np # list of list of strings … Read more
From your question name = input(“What is your name: “) age = int(input(“How old are you: “)) year = str((2014 – age)+100) print(name + ” will be 100 years old in the year ” + year) Your code is just fine, change your input to raw_input for name variable. NOTE: raw_input returns a string, input … Read more
