In [48]: cat pendulum_semicolon.txt
  File "<ipython-input-48-e05dcfac3bb1>", line 1
    cat pendulum_semicolon.txt
SyntaxError: invalid syntax

In [49]:  pendsemi=loadtxt("pendulum_semicolon.txt")
ValueError: could not convert string to float: '1.0000e-01;6.9004e-01'

In [52]: open("D:\python FDP\pendulum_semicolon.txt")
Out[52]: <_io.TextIOWrapper name='D:\python FDP\pendulum_semicolon.txt' mode='r' encoding='cp1252'>

cat is a linux specific command. In windows, type !type pendulum_semicolon.txt inside ipython terminal
Try to add a delimiter in the loadtxt command. The command should be 
pendsemi=loadtxt("pendulum_semicolon.txt", delimiter=";")
