How to install sympy package in python

Question

I am a beginner to python, I wanted to symbolic computations. I came to know with sympy installation into our pc we can do symbolic computation. I have installed python 3.6 and I am using anaconda nagavitor, through which I am using spyder as an editor. now I want to install symbolic package sympy how to do that. I checked some post which says use 'conda install sympy'. but where to type this? I typed this in spyder editor and I am getting syntax error. thankyou

Solution 1

Agree with Dixit.

First Solution:

It's okay to use pip3 install sympy on MacOS.

1. List item
2. Open your "Terminal".
3. Input pip3 install sympy and press enter.
4. It will automatically download and install the Sympy Package.

Second Solution:

Using git. # Notice: Before install Sympy, it's necessary to install "mpmath". Like the First Solution,

• 1) Open "Terminal";
• 2) Input pip3 install mpmath

After installing "mpmath", then,

1. List item
2. Open your "Terminal" on MacOS or "win+r", then input "cmd" in Windows.
3. Input "git clone git://github.com/sympy/sympy.git" and press enter;
4. Input "python setup.py install"

After finish installation, you can open the Python IDLE and try:

from sympy import Symbol, cos
x = Symbol('x')
e = 1/cos(x)
print(e.series(x, 0, 10))
# Result
# 1 + x**2/2 + 5*x**4/24 + 61*x**6/720 + 277*x**8/8064 + O(x**10)

If the code works, it shows that your "Sympy" package has already been installed.

Solution 2

In anaconda navigator:

1. Click Environments (on the left)
2. Choose your environment (if you have more than one)
3. On the middle pick "All" from dropbox ("installed" by default)
4. Write sympy in search-box on the right
5. Check the package that showed out
6. Click apply

@acoustic python Did you try "pip3 install sympy"? It also works in Windows.

Finally I got the result. But the code is running in the spyder editor , but not running in the python shell. it is still showing module not found error

[pandalai]

Maybe the package still has not been installed at the path of Python-3.6. Anyway, if you accept my answer, please tick it. Thanks!
