# Cheat sheet

## Scientific content

Quick tricks for generating scientific content.

### DOI (Digital Object Identifier)

Generate a fake DOI - a string formatted as `10.####/####-####`:

```python
from fake import FAKER

FAKER.randomise_string(value="10.####/####-####")
# '10.4613/4636-8596'
```

---

### ISSN/EISSN (International/Electronic Serial Number)

Generate a fake ISSN/EISSN - a string of eight digits with a hyphen between
the groups of four digits:

```python
from fake import FAKER

FAKER.randomise_string(value="####-####")
# '6160-6320'
```

---

### ORCID (Open Researcher and Contributor ID)

Generate a fake ORCID ID - four groups of four digits separated by hyphens:

```python
from fake import FAKER

FAKER.randomise_string(value="####-####-####-####")
# '6827-5849-5672-2984'
```

---

### arXiv Identifier

Generate a fake arXiv ID in the modern format (e.g., `2101.12345`):

```python
from fake import FAKER

FAKER.randomise_string(value="####.#####")
# '0206.74568'
```

---

### Scientific article metadata

Generate fake metadata for a scientific article, including a title, a
list of authors, journal name, publication year, and keywords:

```python
from fake import FAKER

article_title = FAKER.sentence(suffix="")
# 'Preferably youre than is now'

authors = [FAKER.name() for _ in range(3)]
# ['Thomas Sajip', 'Ben Gust', 'Christian Dragon De Monsyne']

journal = FAKER.string_template("Journal of {word} Studies")
# 'Journal of Better Studies'

publication_year = FAKER.year(start_year=1970, end_year=2024)
# 2001

keywords = FAKER.words()
# ['Youre', 'Guess', 'Is', 'Lets', 'Of']
```

---

Generate a fake short abstract:

```python
from fake import FAKER

abstract = FAKER.string_template(
    """
    {date(start_date="-7d")}

    # Title: {sentence(nb_words=6, suffix="")}

    ## Authors: {name}, {name}, {name}

    ## Abstract

    ### Introduction
    {text(nb_chars=200, allow_overflow=True)}

    ### Objective
    {text(nb_chars=200, allow_overflow=True)}

    ### Methods
    {text(nb_chars=200, allow_overflow=True)}

    ### Results
    {text(nb_chars=200, allow_overflow=True)}

    ### Conclusion
    {text(nb_chars=200, allow_overflow=True)}

    Keywords: {word}, {word}, {word}
    """
)
```

Sample output:

```text
2025-04-08

# Title: Of dutch a cases silenced never

## Authors: Michael Dalke, Barry Dragon De Monsyne, Victor Diederich

## Abstract

### Introduction
Implicit idea of better idea. And special errors implicit is. Is are
explicit better complicated. More nested cases honking lets. Never of
beautiful than be. Explicit way namespaces better explicitly.

### Objective
Better implementation it complex by. Way bad preferably do a. Is than
temptation good although. The guess if ambiguity the. Better its sparse
and special. Is than is preferably than. Of although do to practicality.

### Methods
Should its than flat to. There than explicit obvious at. Idea readability
idea is ugly. Only refuse now the now. Complex its one complicated of. The
flat obvious temptation dutch. Flat is python tim simple.

### Results
Way there guess than to. Pass is and are beautiful. It nested that
although obvious. Better better simple idea than. Is not better great
simple. The complex although explain of. Than special than than obvious.

### Conclusion
Explicitly explain more enough honking. To counts dense should pass.
Obvious unless is if be. Be implementation good implementation now.
Better if than now face. At complex to although than. Than may of better.
