math - Using Wolfram Alpha in Python? -


i'm developing program in python. part of process involves solving equation in x in form ax^1.2 + bx^2.2 + cx^3.2 + dx^4.2 - s = 0, a, b, c, d , s known variables.

i've installed wolfram alpha package using pip, , working in ide pycharm. code correctly calculates value of x, think stored string, rather float, because 'answer' outputted "x = 385.279", instead of numerical value. in order use x value in further calculations, need convert float removing "x = " part. know how in python, wondering how done using wolfram alpha language?

this section of code far:

client = wf.client("app_id") #app_id app id  q = "solve 274770*x**1.2 + 8271.8*x**2.2 + 79.555*x**3.2 + 0.22184*x**4.2 -  35435557377 = 0" res = client.query(q) answer = next(res.results).text print(answer)  ra1 = answer print("ra1:", ra1)  ra2 = (k*r0**eta) / (measured_density_a*(h*ra1**0.2 + g*ra1**1.2 +  i*ra1**2.2 + e*ra1**3.2)) print("ra2", ra2)

these variables calculated used in code:

k = 653.1494097422409 eta = 3.9074130500231186 alpha = 1.2 r0 = 92 measured_density_a = 10 measured_density_b = 7 measured_density_c = 12 power = eta-alpha

this output when run code:

x = 385.279 ra1: x = 385.279

traceback (most recent call last): file "c:/users/nadia/pycharmprojects/particle_energy/energy_code/complete_code_wolfram.py", line 282, in ra2 = (k * r0 ** eta) / (measured_density_a * (h * ra1 ** 0.2 + g * ra1 ** 1.2 + * ra1 ** 2.2 + e * ra1 ** 3.2))

typeerror: unsupported operand type(s) ** or pow(): 'str' , 'float'

thank in advance!

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
