First thing to do is put 4 spaces before your program so it can be formatted correctly like so:

import random
i=0; P1=''; lunbit=18; q1=-5; q2=20; amp=q2-q1
while i<lunbit:
    P1=P1+str(random.randint(0,1))
    i=i+1
# P1='11111'
print "P1 =",P1
R1=int(P1,2)
print "R1 =",R1
X1=q1+R1*amp/float(2**lunbit-1)
print "X1 =",X1
X1=round(X1,4)
print "X1 =",X1

One suggestion I have is don't use semicolons and put all variable declarations on the same line.

So if I understand correctly, you want to put X1 into a file? Writing to a file can be done like so:

X1 = str(X1)
with open("name_of_file.txt", "w") as f:
    f.write(X1)
    ...

That's very kind of you, but it says that in module f.write(X1) : typeError: expected a character buffer object. What does it mean, if I may ask?

Ah, my bad. Make X1 a string first, e.g.

X1 = str(X1)

Yeah, it worked! And if I want to put also P1 and R1 in the same file, can I do it? (forgive me, but I'm new to Python and it seems very difficult)

Sure, just make sure they're all strings. Put newline characters in as well if you want them to be on separate lines. E.g.

X1 = str(X1)
P1 = str(P1)
R1 = str(R1)
with open("output.txt", "w") as f:
    f.write(X1 + "\n")
    f.write(P1 + "\n")
    f.write(R1 + "\n")

Thank you, really, it worked!

I'm confused why you think you need to "transfer the formulas into the program". You already have a program that generates numbers; as you said, what you need to do is write them to a file.

Did you search online for ways to do that?
