I have a DataFrame with two columns. One column contains string values that may or may not include numbers (integer or float). Sample: import pandas as pd import numpy as np data = [(‘A’, ‘>10’), (‘B’, ’10’), (‘C’, ‘<10’), (‘D’, ’10’), (‘E’, ’10-20′), (‘F’, ‘20.0’), (‘G’, ‘25.1’) ] data_df = pd.DataFrame(data, columns = [‘name’, ‘value’]) ..

I’m a freshie. I would like to convert a numeric string into int from a sublist in Python. But not getting accurate results. 😔 countitem = 0 list_samp = [[‘1′,’2′,’blue’],[‘1′,’66’,’green’],[‘1′,’88’,’purple’]] for list in list_samp: countitem =+1 for element in list: convert_element = int(list_samp[countitem]) list_samp[countitem] = convert_element Source: Python.. I want to code this matrix A in python. I could do it like this: O = np.zeros((4,4)) I_neg = -1 * np.identity(4) A_1 = A_1() A = [[A_1, I_neg, O, O], [I_neg, A_1, I_neg, O], [O, I_neg, A_1, I_neg], [O, O, I_neg, A_1]] print(A) But I don´t know if that works, since the result ..

i’ve got a task to create bezier curve with given n points [1,10,20…1000]. i want to use cubic bezier to find the whole curve. first problem for me is that i want to take 2 points and then find for them (between them) the 2 control points but i dont know how to find the .. I am trying to get the following result using (numerical) double integration of the two partial derivatives: def deriv_y(x,y): return -2*x*y*np.exp(-x**2-y**2) and def deriv_x(x,y): return (1-2*x**2)*np.exp(-x**2-y**2) The function is an introductory example suitable for novices. The derivatives and some properties are provided here by Wolfram Alpha. This function is also used by this tutorial "3D ..

can anyone tell me how can I do the augmentation of the numerical dataset in python? I am doing a thesis my dataset size is small I want to increase it my dataset is a health-based Heart disease dataset it has numerical values of blood pressure and heart rate. Source: Python..

I have the following integral (inspired by this question) involving two real variables a and b (and the imaginary unit I): f = integrate(exp((-a*t**2+I*b*t)/(3*t**2+1)+I*t*x)*(x/(3*t**2+1)), (t, -oo, oo), (x, 0, oo)) I would like to iterate both variables a and b, let us say in the range from -10 to 10, e.g. for a in range(-10,11): ..
