Why Does My Python Execution Fail with a Blank Line in Git Bash?

Python Refuses to Launch in Git Bash

When attempting to execute Python within Git Bash (Windows), you may encounter a puzzling blank line instead of the expected Python initialization message. While the error message remains elusive, Python remains inaccessible.

Troubleshooting Steps:

• Verify Environmental Variables: Ensure that the PATH variable in your environmental variables includes c:python27.

Temporary Solution:

• Create an alias within Git shell: alias python='winpty python.exe'. This command creates an alias for the Python executable that lasts for the current shell session.

Permanent Solution:

Method 1: CLI

• Append the alias to your .bashrc file using the CLI:

  echo "alias python='winpty python.exe'" >> ~/.bashrc

Method 2: Text Editor

• Create a .bashrc file if it doesn't exist: cd ~; touch .bashrc.
• Open .bashrc in your preferred text editor and add the alias.
• Apply the changes using source .bashrc or restart the shell.

Update for Newer Git Versions:

Git versions now leverage .bash_profile instead of .bashrc. Ensure you do not overwrite the initialization block used by both Git and Conda when modifying .bash_profile.
