    For Python3

    import cmath

c = complex(input())

print(abs(c))
print(cmath.phase(c))

    from math import sqrt,atan,pi

z=complex(input())

x=z.real 
y=z.imag 

r=sqrt(x**2+y**2)

if x<0 and y>=0:
    theta=atan(y/x)+pi
elif x<0 and y<0:
    theta=atan(y/x)-pi
elif x>0 and y<0:
    theta=atan(y/x)
elif x>0 and y>=0:
    theta=atan(y/x)
elif x==0 and y>0:
    theta=pi/2
elif x==0 and y<0:
    theta=-pi/2
else:
    theta=0

print(f'{r}\n{theta}')

    In barely few lines...

    import cmath
complex_num = complex(input())
print(abs(complex_num))
print(cmath.phase(complex_num))

    from cmath import phase
z = input()
print(abs(complex(z)), phase(complex(z)), sep='\n')
