I am meeting a problem with 2 functions
The 1st one
the first function job: clean a string and
at the end, it calls the function def pi_digits():
in order to recover the value of pi .
This sequence gives a message <generator object pi_digits at 0x00000223B0738580>
which I cannot manage
[python]
#---------------------------------- init
mytestr = "Afdc ERFGDS 12547 éàè,;:!) "
fenet_1.insert("1.0",mytestr)
DIGITS = 200

the right value - who has a clue
many thanks?

You changed the function pi_digits.
When running alone, you wrote pi_digits like this:
def pi_digits(x):
k,a,b,a1,b1 = 2,4,1,12,4
while x > 0:
p,q,k = k * k, 2 * k + 1, k + 1
a,b,a1,b1 = a1, b1, p*a + q*a1, p*b + q*b1
d,d1 = a/b, a1/b1
while d == d1 and x > 0:
yield int(d)
x -= 1
a,a1 = 10*(a % b), 10*(a1 % b1)
d,d1 = a/b, a1/b1When combined with the other function you added code to the bottom of the function.
def pi_digits():
print("into pi_digits")
k,a,b,a1,b1 = 2,4,1,12,4
while x > 0:
p,q,k = k * k, 2 * k + 1, k + 1
a,b,a1,b1 = a1, b1, p*a + q*a1, p*b + q*b1
d,d1 = a/b, a1/b1
while d == d1 and x > 0:
yield int(d)
x -= 1
a,a1 = 10*(a % b), 10*(a1 % b1)
d,d1 = a/b, a1/b1
digits = [str(n) for n in list(pi_digits(DIGITS))]
str_pi='{}.{}'.format(digits.pop(0), "".join(digits))
context = decimal.Context(prec=100)
decimal.setcontext(context)
pi = decimal.Decimal(str_pi)
# return pi.lstrip(pi[0:4])
## print((pi) , " = pi en binaire - lig 123")
return piThis code does not belong in pi_digits. This code uses pi_digits to create a decimal pi.
digits = [str(n) for n in list(pi_digits(DIGITS))]
str_pi='{}.{}'.format(digits.pop(0), "".join(digits))
context = decimal.Context(prec=100)
decimal.setcontext(context)
pi = decimal.Decimal(str_pi)
# return pi.lstrip(pi[0:4])
## print((pi) , " = pi en binaire - lig 123")
return piYou could write a new function that uses pi_digits and returns pi with the specified number of digits.
import decimal
def pi_digits(x):
"""Generates digits for pi."""
k,a,b,a1,b1 = 2,4,1,12,4
while x > 0:
p,q,k = k * k, 2 * k + 1, k + 1
a,b,a1,b1 = a1, b1, p*a + q*a1, p*b + q*b1
d,d1 = a/b, a1/b1
while d == d1 and x > 0:
yield int(d)
x -= 1
a,a1 = 10*(a % b), 10*(a1 % b1)
d,d1 = a/b, a1/b1
def decimal_pi(precision):
"""Return pi to the specified precision."""
digits = [str(n) for n in list(pi_digits(precision))]
str_pi='{}.{}'.format(digits.pop(0), "".join(digits))
context = decimal.Context(prec=100)
decimal.setcontext(context)
return decimal.Decimal(str_pi)
print(decimal_pi(200))Or you can integrate the generator if it isn't used elsewhere.
def decimal_pi(precision):
"""Calculate pi to precision number of digits."""
x = precision
digits = []
k, a, b, a1, b1 = 2, 4, 1, 12, 4
while x > 0:
p, q, k = k * k, 2 * k + 1, k + 1
a, b, a1, b1 = a1, b1, p * a + q * a1, p * b + q * b1
d, d1 = a / b, a1 / b1
while d == d1 and x > 0:
digits.append(str(int(d)))
x -= 1
a, a1 = 10 * (a % b), 10 * (a1 % b1)
d, d1 = a / b, a1 / b1
digits.insert(1, ".")
decimal.setcontext(decimal.Context(prec=precision))
return decimal.Decimal("".join(digits))
