loadtxt() function. The loadtxt() function is used to load data from a text file. Each row in the text file must have the same number of values.
How do I import a text file into Numpy?
Use numpy. loadtxt() to load a text file to a NumPy array of strings. Call numpy. loadtxt(fname, dtype) with fname as the file name to be read and dtype as str to return a NumPy array of the strings contained in fname .
How do I read a text file in Numpy?
To import Text files into Numpy Arrays, we have two functions in Numpy:
- numpy. loadtxt( ) – Used to load text file data.
- numpy. genfromtxt( ) – Used to load data from a text file, with missing values handled as defined.
What is import NumPy as NP?

Which of the following imports the Odeint function Python?
Answer: The Python code first imports the needed Numpy, Scipy, and Matplotlib packages. The model, initial conditions, and time points are defined as inputs to ODEINT to numerically calculate y(t). An optional fourth input is args that allows additional information to be passed into the model function.
