No, it’s called unpacking (look it up, it’s common in python) It’s shorthand for W_grad = grad_fn(X_train,y_train,W,b)[0] b_grad = grad_fn(X_train,y_train,W,b)[1] It will only work if grad_fn(…) returns an iterable with two elements, otherwise it will fail. solved Two variables with the same value in Python
Be careful cls is typically used for classmethods for example like this: class Person: def __init__(self, name, age): self.name = name self.age = age @classmethod def fromBirthYear(cls, name, birthYear): return cls(name, date.today().year – birthYear) So it is better to not use it for your own class names to avoid confusion. Comming to your question. In … Read more
Did you mean to hoist the input() in front of the loop? mylist = [‘good’, ‘great’, ‘fantastic’, ‘fine’] q = input(‘how are you?’) for word in mylist: if q == ‘Im ‘ + word: print(‘Have a nice day’) break else: print(‘Sorry for that’) Example sessions: how are you?Im good Have a nice day how are … Read more
This sounds like you need a remap function (I’ve answered this in JavaScript before). def remap( value, source_min, source_max, dest_min=0, dest_max=1, ): return dest_min + ( (value – source_min) / (source_max – source_min) ) * (dest_max – dest_min) Now, for instance to map the value 250 from between 0 to 500 to the range 0 … Read more
So I had a little bit of a play around and I think this is what your after. I also changed your code a little bit as I always feel its best to put self infront of all widgets on multiclass applications. import tkinter as tk class FirstFrame(tk.Frame): def __init__(self, master, **kwargs): tk.Frame.__init__(self, master, **kwargs) … Read more
the way your code is structured, you iterate over the matches in your for loop, then, when the loop is finished, you save the last match in your CSV. You probably want to write each match in your CSV instead, inside the for loop. try to replace the last lines of your code (starting at … Read more
You could use isdigit to check if your string contains digits Example 1 print( all( not c.isdigit() for c in “String doesn’t contain any numbers.” ) ) True Example 2 print( all( not c.isdigit() for c in “String 2 doesn’t contain any numbers.” ) ) False solved How to program to only input words and … Read more

Because you change the question here is the updated answer: See comments in code import pandas as pd import matplotlib.pyplot as plt from matplotlib import style style.use(‘ggplot’) %matplotlib inline # read your dataframe and sort df = pd.read_clipboard() df.drop(columns=[‘length’], inplace=True) df.rename(columns={‘Text.1’: ‘Text length’}, inplace=True) df.sort_values([‘Text’, ‘Tag’, ‘Time’], inplace=True) x = list(df[‘Time’]) # set x axis … Read more
I am also not sure if I see what you mean. Furthermore if I follow your example, should this not be sita and lia with a 0 and not 1? indra and fajar start with 0, too. Anyhow. This might help: d = [{‘id’: ‘1’, ‘nama’: ‘fajar’}, {‘id’: ‘2’, ‘nama’: ‘fajar’}, {‘id’: ‘3’, ‘nama’: ‘fajar’}, … Read more
Best way to visualize a dependent variable as a function of two other independent variables, each of them is a column of a datafarme? solved Best way to visualize a dependent variable as a function of two other independent variables, each of them is a column of a datafarme?
I was looking to keep the 95th percentile not the percentage. Hence the solution is: get the frequency of each part number and add it to the dataframe repair[‘FREQ’] = \ repair.groupby(‘PART_NO’, as_index=False)[‘PART_NO’].transform(lambda s: s.count()) repair.head() filter out rows of repair where repair.freq is greater than or equal to the 95th percentile: 19600 repair = … Read more
You would probably need to use a regular expression to find lines that contain the values you want and to extract them. These lines can then be written in CSV format using Python’s CSV library as follows: import re import csv with open(‘log.txt’) as f_input, open(‘output.csv’, ‘w’, newline=””) as f_output: csv_output = csv.writer(f_output) csv_output.writerow([‘Iteration’, ‘loss’]) … Read more
Here is how you can use a loop to get input, and append the burger prices to a list: burgerPrices = [] for n in range(3): burgerPrice = int(input()) burgerPrices.append(burgerPrice) cokePrice = int(input()) spritePrice = int(input()) current = [burgerPrice+cokePrice for burgerPrice in burgerPrices]+\ [burgerPrice+spritePrice for burgerPrice in burgerPrices] print(min(current) – 50) Or even better, a … Read more
