Python | sympy.subs() method
With the help of sympy.subs()
method, we can substitute the value of variables in the various mathematical functions by using the sympy.subs()
method.
Syntax : sympy.subs(source, destination)
Return : Return the same expression by changing the variable.
Example #1 :
In this example we can see that by using the sympy.subs()
method, we can substitute the value of existing variable to the new variable.
from sympy import *
x, y = symbols( 'x y' )
gfg_exp = cos(x) + 1
gfg_exp = gfg_exp.subs(x, y)
print (gfg_exp)
|
Output :
cos(y) + 1
Example #2 :
from sympy import *
x, y = symbols( 'x y' )
gfg_exp = cos(x) + 1
gfg_exp = gfg_exp.subs(x, 0 )
print (gfg_exp)
|
Output :
2
