绘制指数 function

Question

I'm relatively new to Python. I'm trying to plot exponential term value ranging between 0 and 100. There is no error indicated with the code but the Plot has no legend(line). Kindly help me. Thank you.

import math
import matplotlib.pyplot as plt

for i in range (0,101):
    m = math.exp(i)
    print("For i = ",i)
    print("(e^i) = ",m)
plt.plot(i,m,'b--',linewidth=3)
plt.ylabel('e^i')
plt.xlabel('i')
plt.show()

You can change your code in this way:

import math 
import matplotlib.pyplot as plt
l = list(range (0,101))
m_l = []
for i in l:
    m = math.exp(i)
    print("For i = ",i)
    print("(e^i) = ",m)
    m_l.append(m)
plt.plot(l,m_l,'b--',linewidth=3)
plt.ylabel('e^i')
plt.xlabel('i')
plt.legend(['m_l'])
plt.show()

With your code, you were plotting just the last values of i and m
