I want to combine multiple values in a single variable into a single-line matrix.

We would like to output the results of the following program as a single-line matrix.
If niter, use a matrix like [1,2,3,4,5,6,7....19,20] to
rnorm is a matrix similar to [1.2340014751660304, 0.9402715810329509..., 1.0].
Thank you for your cooperation.

import path as ma

d = 2500
x = 2500  
area=100   
e=5e5   
f = 0     
resid = 0     
nincr = 1      
fincr=1.5e7  
cnorm = 1e-20  
meter = 20     

lzero=ma.sqrt (x**2 + d**2)                 
vol=area*lzero                          
stiff=(area/lzero)*e*(x/lzero)*(x/lzero)   
for incrmin range (1,nincr+1):
    f = f + fincr                     
    resid=resid-fincr                 

rnorm = cnorm*2                             
niter = 0
while(rnorm>cnorm) and (niter<miter)):
    niter=niter+1
    u=resid/stiff
    x = x + u
    l=ma.sqrt(x*x+d*d)
    area=vol/l
    stress=e*ma.log(l/lzero)
    t=stress*area*x/l
    resid = t-f
    rnorm=abs(resid/f)
    stiff=(area/l)*(e-2*stress)*(x/l)*(x/l)+(stress*area/l)

    print(niter)
    print(rnorm)

This is what it looks like when it comes to moving code: rnorm[-1] takes out the last element of rnorm.I will write down only the second half of the change.

rnorm=[cnorm*2]                             
niter = [0]
while((rnorm[-1]>cnorm) and (niter[-1]<miter)):
    niter.append(niter[-1]+1)
    u=resid/stiff
    x = x + u
    l=ma.sqrt(x*x+d*d)
    area=vol/l
    stress=e*ma.log(l/lzero)
    t=stress*area*x/l
    resid = t-f
    rnorm.append(abs(resid/f))
    stiff=(area/l)*(e-2*stress)*(x/l)*(x/l)+(stress*area/l)

print(niter)
print(rnorm)
