The Python function numpy.loadtxt() loads data from a text file. In this text file, each line must have the same number of values.

**Basic composition**

Below is the main syntax of the numpy.loadtxt() function in Python:

numpy.loadtxt(name, dtype=’float’, comment=’#’, delimiter=Not, converters=Not, skiprows=0, usecols=Not, unpackpack=False, ndmin=0, encoding=’bytes’)

And the parameters are as follows:

Settings | Description |

Name | It can be a file, a filename or a generator to read. If there are generators, they must return a string of bytes for Python 3k. If the file extension is .gz or .bz2, the file will be decompressed first. |

Select | Default setting = float, OPTIONAL]. This is the type of data in the resulting table. |

Remarks | Default = ‘#’, OPTIONAL]. Sharks to mark the beginning of a comment. |

Limiter | [Standard = No, OPTIONAL]. Cord used to separate values. |

Converter | [Standard = No, OPTIONAL]. Column number of the dictionary display for the function that converts the row in the column to the desired value. |

exists | Default setting = 0, OPTIONAL]. Pass the lines first |

juzecoles | [Standard = No, OPTIONAL]. The columns start with 0, with usecols= (1,5,7) the 2nd, 6th and 8th columns are read. column deleted. |

**Returned value**

This function allows you to download data from a text file.

**Examples**

Below you will find some examples:

**Example 1**

# Python program to illustrate the loadtxt() function
The input is as deaf as phtht # StringIO, which behaves like a file object of io-import StringIO demo ring = stringIO(10 20 20 30 \n40 50 60) Result = np.loadtxt (demo ring) |

The conclusion for the above programme is given below:

[[ 10. 20. 30.]

[ 40. 50. 60.]]

**Example 2**

# Python program to illustrate the loadtxt() function
The input is as deaf as phtht # StringIO, which behaves like a file object of io-import StringIO demo ring = StringIO(10, 20, 30, 40\n50, 60, 70, 80) v, x, y, z = np.loadtxt(demostring, separator =’, ‘, usecols =(0, 1, 2, 3), Unpack = Correct) pressure(v is : , v) pressure (x is : , x) printout (y is : , y) pressure(z is : , z) |

The conclusion for the above programme is given below:

Z is: x is: 20. 60: [30. 70.] z is: [30. 70.] z is: [10. 50.] Yes, 20. 60.]y is: [30. 70.]z is: [10. 50.]x is: 20. 60.]y is: 30. 60.]y is: 30. 70.]z is: 30. 70.]z is: 10. 50.]x is: 20. 60: [ 30. 60.] [ 20.] : [ 40. 80.]
