### Install
|
<details>
|
||||||
Copy the script to your project and import it with:
|
<summary>
|
||||||
|
<h3 id="production" style="display: inline">

|
|
||||||
`import progressbar`
|
#### Prerequisites
|
||||||
|
- [Python](https://www.python.org/downloads/)
|
||||||
|
|
||||||
or
|
#### Instructions
|
||||||
|
1. Download and add script to project: `curl https://git.zakscode.com/ztimson/py-bar/raw/branch/develop/progressbar.py`
|
||||||
|
2. Use in python script:
|
||||||
|
|
||||||
`from progressbar import Progressbar`
|
```python
|
||||||
|
from progressbar import Progressbar
|
||||||
|
|
||||||
### Quick Start
|
for i in Progressbar(100):
|
||||||
Use in a forloop:
|
...
|
||||||
|
|
||||||
`for i in Progressbar(100)`
|
# OR
|
||||||
|
|
||||||
Dont like it auto writing to the stdout? Do it your self.
|
progress = Progressbar(100, display=False) # Output manually
|
||||||
|
|
||||||
```
|
|
||||||
progress = Progressbar(100, display=False) # display false stops the auto writing
|
|
||||||
for i in progress:
|
for i in progress:
|
||||||
print(str(progress)) # using the to string will maunually write it
|
print(str(progress)) # Print progress bar
|
||||||
|
...
|
||||||
```
|
```
|
||||||
|
|
||||||
Maybe you dont want to use it as an iterable and you just want a progressbar. You can manually control its progress. Example, you want to view download progress:
|
</details>
|
||||||
|
|
||||||
```
|
## Documentation
|
||||||
progress = Progressbar(download_size, unit=" MB/s") # create the object
|
|
||||||
|
|
||||||
...
|
