Tell us what’s happening:
I have finished updating my code but when I run the code it tells me, ModuleNotFoundError: No module named ‘pandas’.

Your code so far

import pandas as pd

    # Read data from file

Try the solutions from the posts in the forums regarding the python data analysis projects and updating your dependencies on replit.com. If that doesn’t work then you’ll need to post a link to your repl.

I updated the dependencies and versions and it worked. Thank you.

4

Can you tell what changes have you made? I am not able to find it in the forum.

This is how my pyproject.toml looks like after making changes:

[tool.poetry]
name = “fcc-demographic-data-analyzer”
version = “0.1.0”
description = “”
authors = [“Your Name you@example.com”]

[tool.poetry.dependencies]
python = “^3.8”
pandas = “^1.3.5”

[tool.poetry.dev-dependencies]

[build-system]
requires = [“poetry>=0.12”]
build-backend = “poetry.masonry.api”

And this is how my poetry.lock looks like:

[[package]]
name = “numpy”
version = “1.24.1”
description = “Fundamental package for array computing in Python”
category = “main”
optional = false
python-versions = “>=3.8”

[[package]]
name = “pandas”
version = “1.3.5”
description = “Powerful data structures for data analysis, time series, and statistics”
category = “main”
optional = false
python-versions = “>=3.7.1”

[package.dependencies]
numpy = [
{version = “>=1.17.3”, markers = “platform_machine != "aarch64" and platform_machine != "arm64" and python_version < "3.10"”},
{version = “>=1.19.2”, markers = “platform_machine == "aarch64" and python_version < "3.10"”},
{version = “>=1.20.0”, markers = “platform_machine == "arm64" and python_version < "3.10"”},
{version = “>=1.21.0”, markers = “python_version >= "3.10"”},
]
python-dateutil = “>=2.7.3”
pytz = “>=2017.3”

[package.extras]
test = [“hypothesis (>=3.58)”, “pytest (>=6.0)”, “pytest-xdist”]

[[package]]
name = “python-dateutil”
version = “2.8.1”
description = “Extensions to the standard Python datetime module”
category = “main”
optional = false
python-versions = “!=3.0.,!=3.1.,!=3.2.*,>=2.7”

[package.dependencies]
six = “>=1.5”

[[package]]
name = “pytz”
version = “2020.1”
description = “World timezone definitions, modern and historical”
category = “main”
optional = false
python-versions = “*”

[[package]]
name = “six”
version = “1.15.0”
description = “Python 2 and 3 compatibility utilities”
category = “main”
optional = false
python-versions = “>=2.7, !=3.0., !=3.1., !=3.2.*”

[metadata]
lock-version = “1.1”
python-versions = “^3.8”
content-hash = “f7d890533084418520a3e3e20ffba5cb5dccc3dfe48a72cb91ec12bab54da358”

[metadata.files]
numpy =
pandas =
python-dateutil =
pytz =
six =

Just compare what you have with this and make the changes and it should work perfectly.
