def get_hidden_card(credit_number, star_count=4):
short_credit_number = str(credit_number[12:16])
return str('*' * star_count + short_credit_number)
print(get_hidden_card(2034399002125581))
As i understand python don't wanna work because he think that str(credit_number[12:16]) is int type, how can i fix it?
The error is:
Traceback (most recent call last):
File "C:\Users\Ivan\PycharmProjects\pythonProject\main.py", line 10, in <module>
print(get_hidden_card(2034399002125581))

short_credit_number = str(credit_number[12:16])

This is must solve your issue

short_credit_number = str(credit_number)[12:16]
return str('*' * star_count + short_credit_number)

I'm studying 'inheritance' in Pycharm.
I just followed tutorial. And it doesn't work. What's the problem
##Chef.py##
class Chef:
def make_chicken(self):
print("The chef makes a chicken")
def make_salad(self):
print("The chef makes a salad")
def make_special_dish(self):
print("The chef makes bbq ribs")
##another.py##
from Chef import Chef
class another(Chef):
##app.py##
from another import another
a = another()
a.make_salad()
run>>>
error message :
Traceback (most recent call last):
File "C:/Users/NEWS1/PycharmProjects/exc/app.py", line 1, in <module>
from another import another
File "C:\Users\NEWS1\PycharmProjects\exc\another.py", line 9

SyntaxError: unexpected EOF while parsing
Process finished with exit code 1
What is the problem....

The issue is in your 'another' class, there's nothing following the colon. You can either add methods to the class or just a 'pass' like so
##another.py##
from Chef import Chef
class another(Chef):
# other content
pass

I have this code that I typed into Python and I'm getting "Syntax error: invalid syntax" for b=Od/T. Does it have to do with how it's defined? How can I fix it
import scipy.integrate as sci
import scipy.constant as scc
import math
import numpy as np
import matplotlib.pyplot as plt
from IPython import get_ipython
get_ipython().run_line_magic('matplotlib', 'inline')
def f(T):
n=6.022*(10**28)
Od=429
V=10**(-3)
ft=lambda x: ((x**4)*math.exp(x)/(((math.exp(x))-1**2))
b = Od/T
a=0
C=9*V*n((T/Od)**3)*scc.k*(sci.quad(ft,a, b.any(),limit=10))[0]
return C
T1=np.arange(5,500,1)
plt.plot(T1,f(T1),'r-')

You're missing a closing parentheses on the previous line:
ft=lambda x: ((x**4)*math.exp(x)/(((math.exp(x))-1**2))
# ^ This parenthesis is never closed.

Error in the line before that. You can try this.
fr=lambda x: (x**4)*math.exp(x)/((math.exp(x))-1**2)

Here is my code:
r = random.randint(1,10)
But for some reason it's giving me the error
NameError: name 'random' is not defined
Other info: Mac, Python, 3.4.0 pylauncher

You have to import the module random:
import random
r = random.randint(1,10)
# ...

>>> import random
>>> r = random.randint(1,10)
>>> r
10

you need to import the random library with the import keyword
import random
random.randint(1,10) #no. between 0 and 10

I am writing a Python script that will print out a random value from a list I have written,
from random import randint
class_list=[0,1,2,3,4,5,5,6,7,8,9,10,11,12]
people_called=[]
randomized_number = random.randint(0,12)
print "debug number" + str(randomized_number)
print "The student is" + str(class_list[randomized_number])
class_list[randomized_number].append(people_called)
However when I run this file I get I get
Traceback (most recent call last):
File "./Code/class list.py", line 4, in <module>
number = random.randint(0,12)
NameError: name 'random' is not defined

from random import randint imports randint from random module. That is, you can just use it as randint. If you would import it as import random, you'd have to use random.randint instead.

When importing using just import random, you must call the function with random.randint().
When using from random import randint, Python lets you call the function with just randint()
